1. a kind of quick-frozen technique of flounder fillets, it is characterised in that: the following steps are included:

(1), balance carries out sabot, plastic covering piece to the flounder fillets of machine-shaping；

(2), it is pre-chilled, the flounder fillets of sabot is put into freezing chamber and are pre-chilled, precooling temperature is -2 DEG C -- 10 DEG C, pre-coo time is 15-20 minutes；

(3)；Freezing, removes shaping plastic sheet, the flounder fillets of sabot is put into mono-frozen machine and are freezed, and cryogenic temperature is -20 DEG C or less.

2. the quick-frozen technique of a kind of flounder fillets according to claim 1, it is characterised in that: preferred pre- in the step (2) Cold temperature is -4 DEG C, and preferred pre-coo time is 15 minutes.

3. the quick-frozen technique of a kind of flounder fillets according to claim 1, it is characterised in that: in the step (3), cryogenic temperature It is -35 DEG C or less.

Technical field

The present invention relates to technical field of aquatic product processing.

Background technique

Sole, also known as flatfish, flatfish are rich in the nutritional ingredients such as protein, vitamin A, vitamin D, calcium, phosphorus, potassium, The content of especially vitamin B6 is rich, and fat content is less.In addition, flatfish is also rich in the main constituents DHA of brain, It is often edible to increase intelligence；Fine and tender taste and pure white, delicious and fertile, tonify deficiency benefit health, therefore the happiness by broad masses Love.

Sole product processing technique includes that raw material is thawed, scaled, hacking deburring, inspection, cleaning, immersion, bonding balance, list The processes such as body is quick-frozen, packaging, metal detection and vanning storage.Product mainly uses direct contact type monomer during quick-frozen Instant freezer, fillet before sending to mono-frozen machine, above cover one layer of plastic sheet, though can radix saposhnikoviae blow away type, out-of-flatness, also influence change The thermal efficiency and chilling rate.

Summary of the invention

In order to solve the above problem existing for the existing quick-frozen technique of sole product, the present invention provides a kind of flounder fillets are quick-frozen Technique.

Present invention technical solution used for the above purpose is: a kind of quick-frozen technique of flounder fillets, including following step It is rapid:

(1), balance carries out sabot, plastic covering piece to the flounder fillets of machine-shaping；

(2), it is pre-chilled, the flounder fillets of sabot is put into freezing chamber and are pre-chilled, precooling temperature is -2 DEG C -- 10 DEG C, pre-coo time It is 15-20 minutes；

(3)；Freezing, removes shaping plastic sheet, the flounder fillets of sabot is put into mono-frozen machine and are freezed, cryogenic temperature It is -20 DEG C or less.

In the step (2), preferred precooling temperature is -4 DEG C, and preferred pre-coo time is 15 minutes.

In the step (3), cryogenic temperature is -35 DEG C or less.

The quick-frozen technique of flounder fillets of the invention, by the way that the sole product of machine-shaping are pre-chilled, and it is quick-frozen in flounder fillets Before remove shaping plastic sheet, effectively improve the quick-frozen time of flounder fillets.

Specific embodiment

The quick-frozen technique of flounder fillets of the invention, comprising the following steps:

(1), balance carries out sabot, plastic covering piece to the flounder fillets of machine-shaping；

(2), it is pre-chilled, the flounder fillets of sabot is put into freezing chamber and are pre-chilled, precooling temperature is -4 DEG C, and pre-coo time is 15 points Clock；

(3)；Freezing, removes shaping plastic sheet, the flounder fillets of sabot is put into mono-frozen machine and are freezed, cryogenic temperature It is -35 DEG C or less.

The flounder fillets of machine-shaping are pre-chilled, instant freezer is entered after pre-cooling, delays the intracorporal evaporator of mono-frozen machine The frosting velocity on surface, by the flounder fillets of pre-cooling, removes to improve the precooling effect of evaporator before entering single-freeze body Shaping plastic sheet improves heat and passes to effect, freezes twice of quick-frozen raising or more.The product quick-frozen time is reduced, point holding sole The intact shape of piece, improves production efficiency.

The present invention is described by embodiment, and those skilled in the art know, is not departing from spirit of the invention In the case where range, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, in religion of the invention It leads down, can modify to these features and embodiment to adapt to particular situation and material without departing from essence of the invention Mind and range.Therefore, the present invention is not limited to the particular embodiment disclosed, fallen with claims hereof Embodiment in range belongs to protection scope of the present invention.
