Dehydration and drying are some of the oldest methods of preserving food and other biological materials such as proteins and both live and dead live microorganisms or their metabolites. The invention disclosed herein seeks a method of further improving the process of preserving biological material by combining the freezing or freeze-drying process with a partial infrared dehydration step. By using infrared radiation energy to perform simultaneous blanching and dehydration, the drying speed is greatly increased and better cellular and molecular integrity is maintained. The invention herein is also particularly useful in connection with cannabis and hemp.

Some embodiments of a coating system can include a conveyor and an infrared panel positioned above the conveyor, where the infrared panel outputs infrared energy toward the conveyor bed, a coating device positioned above a brush bed that dispenses coating material towards the brush bed, wherein the brush bed is configured to receive products; and a drying station comprising a rolling conveyor downstream from the brush bed.

A method for producing a purée from a food product, comprising the following steps: refining the food product up to obtaining a purée; de-activating the enzymes by heating the purée, in order to prevent oxidation of the purée. The step of de-activating the enzymes comprises the step of passing an electric current through the purée between electrodes of a first ohmic heater (31).

This invention relates to food processing and, in particular, blanching and dehydration of foods. Conventional blanching and dehydration requires use of steam and forced hot air. This invention is the first to effectively use infrared radiation energy to perform simultaneous blanching and dehydration of fruits and vegetables. Since this technology does not involve the addition of steam or water in the process of blanching, it has been named “infrared dry-blanching” (IDB) technology. IDB is intended to be a replacement for current steam, water and/or microwave blanching methods. It can be used to produce many kinds of value-added dried, refrigerated, frozen and dehydrofrozen foods such as fruit and vegetable products. In general, the advantages of IDB include (1) uniform heating which enhances energy efficiency and limits damage from over-heating, (2) capability of zone heating to address differential density, (3) ability to treat large or small lots with the same piece of equipment, (4) portability, since equipment can be built on wheels, and (5) a safe, non-toxic process with no harmful side-effects to humans or the environment.
