Method and apparatus for the preparation of a crisp food product
A crisp food product is prepared in a first phase from thin food pieces of raw fruit, vegetable or gelatinizable proteins, by blanching them (if necessary) and drying them. A second phase takes place in a vacuum chamber, where the dried thin food pieces are exposed to heat to expand them, are quickly removed from the heat source and are cooled, before being removed from the vaccuum.

Novel infrared dry blanching (IDB), infrared blanching, and infrared drying technologies for food processing
InactiveUS20060034981A1Simple processShorten the timeMilk preservationDough treatmentSide effectVolumetric Mass Density
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.

Method for improving reheated texture of frozen prepared tuberous vegetables
InactiveCN106857802AReduce contentHigh glass transition temperatureFruits/vegetable preservation by freezing/coolingFruits/vegetable preservation by blanchingAdditive ingredientGlass transition
The invention relates to a method for improving the reheated texture of frozen prepared tuberous vegetables, belonging to the technical field of agricultural product processing. The whole reheated texture improvement process of the frozen prepared tuberous vegetables is completed by combining raw material pretreatment and low-frequency ultrasonic-assisted osmotic dehydration with blanching, quick-freezing, glass state freezing storage and reheating. By adopting the low-frequency ultrasonic-assisted osmotic dehydration, the method increases the glass-transition temperature of the tuberous fruits and vegetables, reduces the damage of ice crystal formation to cell structures in a freezing process, can be used for freezing at the glass-transition temperature, and maintains the sensory quality and nutritional ingredients of the vegetables to a greater extent. Furthermore, multiple methods are adopted for cooperative reheating at the later period, so that the materials can be rapidly and stably reheated, and the change of the reheated texture and nutritional quality of the vegetables can be improved.

Dried fresh jujube slices and energy-saving process technology for differential pressure expansion drying
PendingUS20190269160A1Difficult to chewIncrease investmentFood coatingFood shapingFreeze-dryingDifferential pressure
A method for processing dried fresh jujube slices includes the following steps: preparing jujube slices, coring and removing stems, quick-freezing and retaining freshness of the jujube slices, thawing frozen jujube slices, protecting color treatment, expanding jujube slices under differential pressure, preparing superfine mixed seasoning powder, and coating of the superfine mixed seasoning powder. For one hand, this method solves problems that the dried fresh jujube slices will be deeply oxidized and brown when dried by the hot air at a high temperature of 90-110° C., the jujube slices with compacted cells will become harder and be difficult to chew because of 6-8 h rapid dehydration. On the other hand, it solves problems that exist in freeze drying at a vacuum degree of 1.3-13 Pa, and at a low temperature of −10-50° C., such as high energy consumption, long processing cycle, high equipment investment, small size of slices, and poor taste.
