Abstract
The invention provides a process for quickly freezing flowering Chinese cabbage. The process comprises the following steps: (1) selecting raw materials of flowering Chinese cabbage for quickly freezing and cleaning; (2) cooling the flowering Chinese cabbage by a wind separator and removing foreign matters; (3) carrying out secondary cleaning treatment on the flowering Chinese cabbage by using an unhairing machine; (4) sterilizing and cleaning the flowering Chinese cabbage by air bubbles, ultrasonic waves and bacteria reduction agents; (5) blanching the flowering Chinese cabbage with weak alkaline water steam by using a spiral blanching machine; (6) cooling the flowering Chinese cabbage quickly through counterflow ice water; (7) dehydrating the flowering Chinese cabbage through cold wind; (8) putting the flowering Chinese cabbage into an ice house for quick freezing; and (9) packaging the flowering Chinese cabbage into bagged products,and freezing below minus 21 DEG C. The process has the advantages of prolonging the eating time of the flowering Chinese cabbage and improving the quality of the flowering Chinese cabbage during quick freezing.
Description
Affiliated technical field
The present invention relates to a kind of processing of farm products technique, especially a kind of tender flower stalk quick forzen processing technology.
Background technology
Quick-frozen fresh vegetables are one of vegetables converted products of international market supply, at present, the raw material of domestic quick-frozen fresh vegetables mainly comprises root, stem, leaf, flower, fruit and edible mushroom, from the raw material of quick-frozen fresh vegetables, leaf vegetables lower, and mainly take spinach as main, also there is not the quick-frozen converted products of tender flower stalk in leaf vegetables.And no matter be domestic or external now, the quality of vegetables quick frozen product is also being improved constantly, in order to solve tender flower stalk quick-frozen processing quality, spy of the present invention provides a kind of tender flower stalk quick forzen processing technology.
Summary of the invention
The object of the invention is to solve tender flower stalk quick-frozen processing quality, spy provides a kind of processing technology of quick-frozen tender flower stalk.
The present invention is achieved in that a kind of tender flower stalk quick forzen processing technology, and process of manufacture comprises following several step: (1) selects quick-frozen raw material tender flower stalk, and cleans; (2) by the winnowing machine processing of lowering the temperature, and remove foreign matter; (3) with unhairing machine, tender flower stalk is carried out to cleaning for the second time; (4) by bubble, ultrasonic wave, bacteria reducing agent, tender flower stalk is carried out to sterilization cleaning; (5) use spiral blanching machine to the blanching of tender flower stalk alkalescence water vapour; (6) by adverse current frozen water, tender flower stalk is cooling fast; (7) tender flower stalk is carried out to processed by cold wind; (8) tender flower stalk is put into icebox, carry out quick freezing; (9) tender flower stalk is packaged into bag, be put in-21 ℃ following freezing.During with the blanching of alkalescence water vapour, temperature is controlled at 89～93 ℃, and the blanching time is 30～35 seconds.When snap frozen, temperature is controlled at below-35 ℃.
Beneficial effect of the present invention is: extend tender flower stalk edible time, improve the quality of tender flower stalk in quick-frozen process.
