INDUSTRIAL METHOD FOR PRODUCTION OF FOOD ICE FROM VEGETAL RAW MATERIAL Russian patent published in 2011 - IPC A23B7/04 

FIELD: food industry.

SUBSTANCE: invention is intended for use in food industry and in household. Vegetal ice is produced industrially mostly of fresh fully ripe vegetal raw material such as berries, vegetables and fruit. Freshly picked raw material is chilled, thoroughly washed and processed. The liquid part is separated from the solid one and separately packaged into containers of elastic frost-resistant polymer film with a specific mesh size for each phase. The solid part of the vegetal raw material is packaged into containers of double-layer film, the spacing transverse dimension varying within the range of 0.02÷0.04 m. Vegetal antioxidants are added to the vegetal raw material solid part whenever required. Containers with fresh vegetal raw material are subjected to shock freezing at a temperature as low as -25÷-45°C air flow rate amounting to 4-12 m/s, or immersed into a liquid chilling medium at a temperature as low as -25÷-45°C. After freezing containers with vegetal raw material are placed into additional package. The latter may repeatedly be opened and closed. Packaged containers are placed into transportation receptacle and delivered for storage at a temperature as low as -25÷-45°C during a term of one year or more. Whenever required, ice bits are taken out of the containers and consumed.

EFFECT: invention ensures high quality of ice thus produced, preservation of vegetal cells membranes, vitamins and other valuable substances.
