DRYCAKE TWISTER

Description

Operation principle of the Drycake Twister

The TWISTER De-packager & Separator allows to separate packaging from food or other organic material, as well as SSO (source separated organics) prior to anaerobic digestion or composting. The versatility of the TWISTER allows to separate organics from can, wrapper, bag, styrofoam, yogurt, plastic bottle or plastic jar packaging.

The de-packaging process starts with a loading phase into a standard 12 cubic yard hopper.  In case of project requirement, the size of the hopper can be sized accordingly.

The hopper has an auger at the bottom that crushes and conveys the material to be separated in the TWISTER compartment. A secondary auger is installed in the hopper in order to avoid bridging and building up of material in the hopper. This auger only starts when bridging is formed and acts as a bag opener.

Once introduced in the TWISTER compartment, the TWISTER effect removes the solids from the organics by lifting them upwards in a circular motion and exits it through the top screw conveyor.

The organics are discharged by gravity. The TWISTER effect is a re-enactment of a waterspout (intense columnar vortex that occurs over a body of water).

This vortex is created by a vertical shaft with propellers. The upward movement of the solids are interrupted by these propellers and the solids are thrown against the stationary filter drum that surrounds this shaft and allows the excess liquid to drain.

Valuable organic waste rather than being discarded in a landfill are now recovered and recycled to generate biogas a natural and clean energy

Manufacture of the Drake Twister

DRYCAKE’s technical department is able to develop all the required design activities from feasibility to as-built. Process Validation can be validated  using our lab or on-site pilot services.

Our equipment is manufactured in high quality Stainless Steel , and is fully customizable according to project requirements and needs.

The production team is composed by assemblers and certified welders, experts in TIG (Tungsten Inert Gas) welding, a process of arc welding with consumable electrode (Tungsten), under protection of inert gas. After the welding processes, the Stainless Steel is passivated by our operators.

Quality control during the entire design process guarantees the compliance with Customer’s technical requirements, good manufacturing practices and compliance with UL and CSA, ASMI, ANSI Standards and certifications.

All equipment is subject to 3rd party witnessed factory acceptance test prior to shipment.

The complete unit is made entirely out of stainless steel, as this selection of materials is essential to a long life of the equipment

Quality Design

• Automatic operation
• No pre-treatment necessary
• Continuous functioning
• Quick and easy installation
• Low energy consumption
• High quality and reliability
• Manufactured in Stainless Steel AISI 304 and 316(L), DUPLEX SS and other  material on demand
• Welding pickled and passivated
• Easy removable covers for hygienic inspection
• Rubber scrapper bolted to screw  to clean drum
• Low and easy maintenance

The patent pending design change to the drum creates 20% more filtration area and thus extra capacity The redesign also creates a 30 % cleaner organics fraction Because of the corrosive environment this next generation separator also is made entirely in stainless steel with the exception of the wearing parts that in Creuabro. The paddles on the vertical twister separator are field replaceable. The hopper can be sized according to customer’s needs. The sophisticated control system is managed by a Siemens or Allen Bradley PLC. For the protection of the downstream equipment, the twister is in most application completed with a grit removal system.

For the protection of the downstream equipment, the twister is in most applications completed with a grit removal system. (SEDITANK-Plastifoat). The SEDITANK removes 95% of the sand and grit larger than 300 micron.
