Production method for continuously formed onion rings

Abstract

The invention discloses a production method for continuously formed onion rings. The production method comprises the following main process steps: selecting fresh white onions; peeling and cleaning the white onions; dicing the white onions by using a dicer; subjecting onion dices to water controlling or mechanical dehydration to realize raw material preprocessing; uniformly mixing the preprocessed onion dices and a binder in proportion in a mixer with stirring; carrying out forming by using a ram-type forming machine so as to obtain onion rings, each weighing 6 to 7 g; spraying a calcium chloride solution and allowing the calcium chloride solution and bonding substances in the accessory material--the binder to undergo hardening and shaping; allowing the shaped onion rings to enter into a powdering machine through a transmission network belt for automatic powdering, then into a starching machine through the transmission network belt for starching, then into a powder wrapping machine for powder wrapping and finally into a tunnel-like frying machine through the transmission network belt for pre-frying; subjecting obtained finished products to oil controlling, cooling and quick-freezing in an individual quick-freezing machine; conveying the quick-frozen onion rings to an automatic packaging machine through the transmission network belt; manually picking out defective onion rings on the transmission network belt; packaging qualified onion rings by using the packaging machine; and carrying out detection and delivery.

Description

technical field

[0001] The invention relates to a production method of formed onion rings, in particular to a continuous production method of formed onion rings. Background technique

[0002] Onions have the effects of nourishing, invigorating the stomach, clearing heat and detoxifying. With the improvement of people's living standards, onion rings are more and more popular as a snack food. With the continuous increase of market demand, the traditional manual production of shaped onion rings can no longer meet the market demand, and the technology of industrialized production of shaped onion rings has become more and more mature and has achieved scale.

[0003] Chinese patent application CN102187985A discloses a production method of onion rings, which includes the steps of raw material processing, batching, forming, quick-freezing, rewarming, pre-flouring, sizing, wrapping, pre-frying, quick-freezing, bagging and testing. Among them, the size of the onion block is 4×4 cm. ...
