WRPF / WRB Wax Removal Bags

The most common Botanical Extraction Process uses chilled ethanol to
soak the plant material and extract the targeted ingredients. This method
requires a winterization step which chills the crude extract down to
temperatures between -20°C to -60°C to cause unwanted waxes and fats
to solidify so they can be easily removed with a mechanical filtration step.

Strainrite’s WRPF (Wax Removal Pre-Filter) and WRB (Wax Removal Bag)
filters were developed to address a need to lower the cost of the dewaxing
step and offer a product that will stand up to temperatures below -20°C.

​Strainrite’s Product Development Team worked closely with CBD and
other botanical extractor customers to perform full scale process testing.
This testing along with customer feedback were critical to determine
the final combination of materials and optimal surface area to improve
the end users’ overall cost of ownership and result in the lowest cost per
gallon of final product.

A typical wax removal process using Strainrite’s Wax Removal Pre-Filter
and Wax Removal Bag is done in stages, using two to three WRPF (Wax
Removal Pre-filter) stages upstream of a WRB (Wax Removal Bag), or
the WRPF (Was Removal Pre-Filter) can be used upstream of an existing
lenticular filter to remove the bulk of the solids load in the first step and
allow the lenticular filter to perform the final polish step and stay on
line longer, thus assuring final filtrate quality while keeping the cost per
gallon produced as low as possible.
