Filtration of Cocoa butter

Cocoa butter filtration was one of the first Cricketfilter® applications in 1988. The Cricketfilter® is a pressure filter with a large specific filtration area due to the shape of the filter elements. The Cricketfilter® is unique because of its patented filter elements, which allow discharge of the filter cake by back pulsing.

 

The Cricketfilter® is used for clarification of cacao butter, directly after the cocoa press. The Cricketfilter® is a proven filter system in this industry and successfully in use at many major cacao producers.

Filtration of Cocoa butter

Cocoa powder is used for chocolate milk or as a topping on hot drinks. Cocoa powder is also the ingredient that makes the difference between brown and white chocolate!

Cocoa butter is used for the production of chocolate as well. Cocoa butter melts around 36°C (97°F) and gives chocolate the smoothness and the characteristic that it melts in your mouth.

Cocoa butter is also used in cosmetics. Especially in ointments and lip balm.

 

Cocoa butter filtration, why is it needed.

 

  • Cocoa butter still contains varying amounts of solids
  • Crude cocoa butter typically still contains 0,2 – 0,5% cocoa powder
  • Our unique Cricketfilter® technology can take out all the powder
  • Powder (slurry) from Cricketfilter® is sent back to the presses
  • Clean butter is cooled and packed in solid blocks

 

The basic filtration cycles in cocoa butter filtration are:

 

  1. Thickening filtration of cacao butter
  2. Filling
  3. Recirculation
  4. Filtration
  5. Backwashing
  6. Sedimentation
  7. Partial emptying
  8. Slurry discharge

 

Cocoa butter has to be clear to meet the quality requirements.

Clarification of cacao butter is thickening filtration. The Cricketfilter® is fed by a top feed. At the end of the filtration cycle, the filter cake is back pulsed and sediments into the filter cone. The cylindrical part of the filter is emptied via the partial drain. Thereafter the cake slurry is drained through the bottom valve. The cake slurry is sent back to the feed tank before the cacao press, avoiding any product loss.

 

Cricketfilter® characteristics

 

  • Closed pressure vessel
  • Filter elements with cloth
  • Elements shaped like a Cricket bat
  • Both direct and cake filtration possible
  • Layer of solids is pulsed of the elements by gas

 

Cricket filter in cocoa butter filtration

 

  • Solids are discharged in a filled filter tank
  • Slurry is collected in the cone, by sedimentation (thickening)
  • Top part of the filter is emptied through side opening
  • Slurry is discharged separately and sent back to the presses
  • Bag filter installed for safety filtration

 

Challenges in cocoa butter filtration:

 

  • Too much solids
  • Too little solids
  • Too short filtration time
  • Uncontrolled pump speed
  • Moisture

 

Our Cricketfilter® is well suited for filtration of cacao butter

 

  • No precoat allowed and needed
  • Direct filtration over filter cloth

In existing factories the Cricketfilter® mostly has replaced filter presses.

Cricketfilter® Technology

Chemical- and food processing industries place highest requirements on process quality, cleanliness, systems reliability, and products quality. In this respect, our process filtration solutions are used, for example, in the production of Sugar, cocoa or edible oils, for the removal of active carbon, catalyst recovery or for the treatment of different chemical intermediates. They filter the finest particles and contaminations from the products and contribute effectively to maximum hygiene, quality, and product recovery.

 

The Cricketfilter technology has been developed to separate solid particles from a liquid in such a way that the solid particles can be discharged if dry matter or a slury. Liquid losses are kept to an absolut minimum. The Cricket filtration process is a batch process based on cake filtration and is fully automated.

 

Filtration Group Cricketfilters are based on the current leading technology for cake filtration. The new developed septum plate range unifies the advantages of PTS polish and Cricketfilters by using the standard type I Cricket element with 1500 mm length, proven drain and top cloths can be used. The range is an excellent solution for processes where space is limited, high flows are combined with limited amounts of solids or for limited flows. Also this range is the answer for most processes where a polish filter is needed. No internal manifolds, therefore no spray nozzle or height indication needed. this results in a lower investment and less maintenance.

 

  • Side outlet, ensuring a completely drainable septum.
  • Improve safety by reducing the use of bag filters.
  • The risk when opening bag filter housings is eliminated. 
  • Space saving through an excellent surface/volume ratio because of unique Cricket element design.
  • Improved cloth mounting thanks to use of the proven Cricket type I element construction.
  • Easy to connect several filters, saving space and investment.
  • Easy to automate, therefore low maintenance required.
  • Very high cleanability due to less internal parts.
