The Kief Thief Dry Sift Extractor

Solventless Extraction Has Never Been So Easy!

Our dry sift, stainless steel kief tumbler produces high-quality extract without the use of water or any nasty solvents.


  • 316 stainless steel mesh screen
  • 100 mesh micron screen drum
  • Sanitary design
  • American made 120 volt motor
  • One-piece stainless steel chassis
  • Rugged & durable for continuous use
  • Polycarbonate dust cover
  • The finest dry sift extractor on the market


Every Kief Thief is handmade in Eugene, Oregon from high quality materials, so you know it is built to last. Don’t settle for labor intensive sift boxes or for similar products made cheaply overseas with many plastic parts. The Kief Thief is the only kief tumbler on the market exclusively made with stainless steel and durable polycarbonate and designed for quick and easy collection.


The size of the sifter drum accommodates processing anywhere from 1 gram to 1 pound of material in a single run. The Kief Thief is designed to gently separate the trichomes, or plant resins, from your desired starting material without altering or damaging the delicate properties of those resins. On average, our kief tumbler produces a yield of 10% to 25% depending on the starting material.


The Kief Thief is comprised of three basic components:

  1. Chassis and Motor
  2. Sifter Drum
  3. Inspection Cover


Chassis and Motor

Of commercial grade construction, the one-piece stainless steel chassis is built for a lifetime of use. The American-made, high-efficiency gear reduction motor turns at the perfect RPM and can run continuously (up to 48 hours!). The Kief Thief requires a properly installed and grounded 120 volt outlet with a functioning 10 AMP breaker.


Sifter Drum

The sifter drum is comprised of a 316 stainless steel mesh screen, tension rods and a stainless steel access cap and bearing shaft. Individual sifter drums are available for purchase. Having multiple sifter drums allows for seamless back to back runs without the need to wait to empty and clean the previously used sifter drum.


Inspection Cover

The polycarbonate inspection cover keeps contaminates out while also catching the resins which do not collect at the bottom of the chassis. It is also clear, so you can watch the magic of The Kief Thief as it happens.



Overview of Solventless Extraction with The Kief Thief

(This is a brief overview. Please make sure to read the detailed instructions here before using)


Using the kief tumbler is very easy. First, use an alcohol solution and lint free towel to clean the collection area of the chassis and the inside of the inspection cover to remove dust and any contaminants. Next, carefully insert your plant material into the sifter drum making sure to wear rubber gloves so as to not contaminate the micron mesh of the sifter drum with skin oils. Re-install the sifter drum on the chassis, slide the inspection cover into place and turn on the tumbler.


The time necessary for extraction will depend on the amount and quality of the material being processed. We recommend running the kief tumbler for at least 30 minutes and as much as 48 hours. Determining the optimal amount of time to produce maximum yield will be something you will need to experiment with to determine. In general, the drier and finer the material is ground prior to running through the Kief Thief, the higher the yield.


Now it’s time to collect the kief. Turn the machine off and remove the inspection cover placing it upside down. Most of the kief will collect at the bottom of the chassis, but some will stick to the sifter drum and inspection cover. Using a fresh business card or piece of stock paper, wipe the sides of the inspection cover and sifter drum. Then, carefully remove the sifter drum and place it upright on a clean surface. Now, you have access to the bottom of the chassis to collect the kief and move it to storage.


Cleaning the Kief Thief once you have collected your yield is super easy. First, use a BPA free plastic bag to cover the sifter drum and turn it upside down to expunge the spent and sifted material (this material can be used for a variety of purposes such as cooking, tinctures or composting). You can then clean the sifter drum while wearing rubber gloves using either a soft-bristled paint brush or an air compressor.


If you use an air compressor, make sure not to touch the mesh screen with the nozzle and do not exceed 30 PSI. If the kief tumbler is still contaminated, you can spray it with a solution of 50% to 95% alcohol. The chassis and inspection cover should also be wiped with the alcohol solution. Once everything has dried, you can reassemble the Kief Thief to start the process over again!

  • Filling the sifter drum with material

  • Open the box and remove the Kief Thief from its packaging.
  • Remove the clear housing cover from the Kief Thief.
  • Locate the black plastic block that is used to hold the bearing shaft in place for shipping. Carefully use a razor knife to cut the zip ties that hold the bearing block in place and remove the block.
  • Put on a pair of rubber gloves before attempting to lift the sifter drum from the chassis. The oils from your hands can  clog and contaminate the screen.
  • You can now carefully lift up and slide the sifter drum free of the square drive adapter connected to the motor and remove the sifter drum from the chassis.
  • Place the sifter drum on a clean surface so that it is sitting upright with the access plate facing upwards. Never set the drum on its side or allow anything to touch the mesh as it can be easily damaged.
  • You can now use a alcohol solution in combination with a lint free towel or wipe to clean the chassis collection area and cover. This should be done to remove any dust, dirt or contaminates prior to using the Kief Thief. Now that the chassis and collection surfaces have been properly cleaned the sifter drum is ready to be filled.
  • Locate and remove the 4 wing nuts that hold the access cover plate in place. Once the cover plate is removed the sifter drum is ready to be filled. We recommend using a large BPA free turkey bag to store, fill and remove material in and out of the sifter drum.
  • Once you have added your desired amount of dry material into the drum, make sure the access plate surface is wiped clean so that the access plate cover can make a good seal.
  • Re install the access plate cover with guide bearing facing outward and firmly tighten the 4 wing nuts.
  • Carefully re install the sifter drum into the chassis by using one hand to hold on to the bearing shaft while the other hand supports the bottom of the side plate. Make sure that the square drive shaft slides into the side plate and that the bearing rests firmly in its support block. Never lift the drum by touching the screen.
  • Once the sifter drum is installed you can now install the clear inspection cover over the sifter drum.
  • With the clear cover in place, locate the the motor rocker switch and place in the OFF position.
  • Locate the power cord and plug it into a properly installed and grounded 120 volt outlet that has a functioning 10 AMP  breaker.
  • Locate the power switch on the Kief Thief motor cover and place into the ON position.
  • The sifter drum will now begin turning and sifting the material.
  • The majority of the sifted material will start collecting directly under the side of the drum that is turning upward.
  • The amount of time that it will take to thoroughly sift and extract will vary depending on the total amount of product being sifted as well as the quality and condition of material. In general the drier and finer the material is ground prior to running through the Kief Thief, the higher the yield. We recommend running the machine for a minimum of 30 minutes and as long as 48 hours on very large runs for maximum yield. Experiment for yourself to see what works best for you. 

Collecting the Kief

  1. Once you have sifted your material thoroughly it is now time to collect your Kief.
  2. Turn the Kief Thief power switch into the OFF position.
  3. Once the power is OFF and the sifter drum has stopped turning you can gently lift off the clear inspection cover. Since the inspection cover will have Kief stuck to it, place the cover upside down on a smooth surface for collection.
  4. We recommend using only a fresh business card or piece of card stock to swipe down the sides of the cover, sifter drum and sifter chassis to collect the kief.
  5. Once the cover and sifter drum have been swiped off you can now remove the sifter drum from the chassis. Once removed be sure to place the sifter drum so that it is standing on end upright on a clean surface. This will allow you access to thourougly swipe down all of the side of the sifter chassis and collection area. 
  6. Once the cover and sifter drum have been swiped off you can now remove the sifter drum from the chassis. Once removed be sure to place the sifter drum so that it is standing on end upright on a clean surface. This will allow you access to thourougly swipe down all of the side of the sifter chassis and collection area. 
  7. Once the chassis has been swiped down and the kief has been collected and put into storage you can now get ready to empty out the spent material from within the sifter drum.
  8. Removing the spent and sifted material from the sifter drum. 
  9. With the sifter drum sitting on its end with the access cover facing upward, remove the 4 wing nuts that secure the access plate.
  10. Once the access plate is removed gently slip a BPA free Turkey bag or trash bag over the top of the drum and pull it downward over the drum. You can then gently flip the drum over while supporting the sides of the side plates and empty out the contents into the bag. This method helps keep dust and particulate from getting into the work area. 
  11. You can now dispose of the spent material.  Since the material may still contains some viable and re usable material many people re use it by either cooking, making a tincture or composting.
  12. The sifter drum is now ready to be refilled, stored or cleaned.

Cleaning the sifter drum

  1. You can use a soft bristled artist paint brush to brush the inside and outside of the sifter drum  to help remove material. If using compressed air make sure that you observe proper safety methods and that the air source is connected to a oil and water separator. Make sure that the air nozzle does not contact the screen and that only 30 PSI or less is used.
  2. If the sifter drum screen has become clogged or contaminated you should clean the screen using either of the above methods and prepare a grain alcohol solution of at least 50% -95% alcohol. Place the solution in an approved spray bottle. Make sure you are using proper skin and eye protection and then with the sifter drum sitting on its end begin to spray down the sifter drum screen from the outside. We recommend setting the drum in a plastic tote or some type of catchment basin to contain and collect the alcohol. Make sure to thoroughly spay down and soak the drum to help remove the plant material, resins and oils that are trapped between the mesh.

  3. Once the sifter drum has been thoroughly cleaned it should be allowed to dry. The sifter chassis and cover can also be wiped down with the alcohol solution for de contamination. The drum can then be re installed for storage in the sifter chassis. 

  4. Do not spray alcohol,water or any other substance in to the motor. It is not designed to get wet and will damage the unit.

I've been using the Kief Thief for over a year now and have ZERO complaints. The guy who makes these is awesome! You can call or email and he responds helpfully. The motor is still running strong after 1 year and it doesn't destroy my flower in the kief'ing process. I highly recommend this bad boy to anyone looking for an easy to use, dependable kief extractor.
