SYSTEM AND METHOD FOR FREEZE-DRYING BATCHES OF SOLID FROZEN PROTEIN RICH FOOD PRODUCTS IN THE INDUSTRIAL SCALE PRODUCTION OF FREEZE-DRIED PROTEIN RICH FOOD, SUCH AS INSECTS, SHRIMPS, DICED MEAT, IN PARTICULAR OF RED MEAT OR POULTRY OR DICED TOFU

摘要

The present invention relates to a system and method for freeze-drying batches of solid frozen protein rich food products in the industrial scale production of freeze-dried protein rich food, such as insects, shrimps, diced meat, in particular of red meat or poultry or diced tofu. The system comprises a vessel with a drawer embodied as an elongated canister having over at least a majority of its length a canister wall that is open at a part of its circumference in cross-section to define a bottom and an opening at the top. The canister is provided with a mechanical mixer comprising at least one mobile blade. A mixer drive motor is provided that connects to a transmission assembly of the canister when received in the vessel, so that operation of the mixer drive motor causes the mobile blade to move and entrain therewith a portion of the batch of food products to increase exposure thereof.
