Abstract
The invention provides a blanching and cooling process for purple waxy corn and relates to the field of food processing. The purple waxy corn enters a blanching tank after being unhusked and sorted, stays for 2-3 minutes and then leaves the blanching tank under drive of a conveying belt; the purple waxy corn is sorted by workers after leaving the blanching tank, and the purple waxy corn damaged by pests is picked out; the sorted purple waxy corn is conveyed to a cooling tank through the conveying belt and is cooled for 5-10 minutes; the purple waxy corn is sorted again by the workers, the corn damaged by pests is picked out, and the sorted corn is air-dried; the corn is wrapped with package bags after being air-dried, then vacuumized, sterilized at high temperature and conveyed to a warehouse. The blanching quality of the corn is improved, and the labor intensity and the cost are reduced.
Description
Technical field
The present invention relates to food processing field.
Background technology
If corn is without blanching cooling processing, the sugar of maize seed, nutrition leak can be caused.Particularly important to the control of water temperature in blanching corn process, the too low meeting of water temperature does not reach the object of blanching; Water temperature over-high can make corn well-done, easily causes loss and larger economic loss in ensuing processing.
Summary of the invention
In order to overcome the above problems, the invention provides a kind of Purple glutinors maize blanching process for cooling, improve the blanching quality of corn, reduce labour intensity and cost.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of Purple glutinors maize blanching process for cooling, comprises the following steps:
The first step: first by the water temp. heating in blanching equipment to 88 DEG C-92 DEG C, a cooling pool inner water is filled simultaneously;
Second step: Purple glutinors maize is shelled, sort after put into accommodation grid on blanching device transmission band;
3rd step: under the drive of transport tape, to hold grid and stops after 2-3 minutes along with blanching pond is left in the drive of transport tape in blanching pond respectively;
4th step: Purple glutinors maize leaves workman's sorting behind blanching pond, will have insect, have damage corn to detect;
5th step: the Purple glutinors maize after sorting is brought cooling bay into by transport tape and cooled 5-10 minute;
6th step: workman sorts again, will have insect, have damage corn to detect, by air-dry for the corn after sorting; Load after air-dry in packaging bag and then carry out vacuum packaging, then high temperature sterilization, put in storage.
Further: in the accommodation grid on described blanching device transmission band, to put 6-8 bag corn.
Further: the packaging bag stated in the 6th step is tailormadepiston vacuum packaging bag that is high temperature resistant, nonhazardous.
Advantageous Effects
In blanching machine equipment, water temperature floats the soup time between 2 ~ 3 minutes between 88 ~ 92 degrees Celsius, be conducive to the nutritional labeling retaining corn like this, if water temperature temperature is lower than 88 degrees Celsius, corn does not have fixing nutritional labeling effect, can not kill in corn ear the insect of hiding and staying; If water temperature is higher than 92 degrees Celsius, can be directly corn is well-done, well-done, can not next step operation be carried out;
According to annual finished product 1200 tons, 1.8 ten thousand common people per ton calculate, and the corn ear finished product proportion of goods damageds processed without overbleach soup machine equipment are about 20%, and economic loss reaches 4,320,000 yuan; Use the corn ear finished product proportion of goods damageds of blanching machine equipment processing about 5%, nearly 3,200,000 yuan of direct saving economy.For company and cooperative society alleviate larger burden.
During with blanching cooling technology processing corn, both improve production efficiency, also improved the quality of corn, reduced labour intensity and cost.After blanching cooling technology comes into operation, blanching cooling device maximum 4 people can operate, and do not need to wait for, can the corn that sorts of Continuous maching.Heat blanching with general steamer, need multiple stage steamer to operate simultaneously, and need many people to operate (every platform steamer needs 3 people's operations).Corn also needs after entering pot to wait for, both loses time, and lavishes labor on again.And corn product quality can not be stablized, and loss is high.The instrument needed also increases, and increases cost.
Detailed description of the invention
The present invention will be further described below, to facilitate the technical staff to understand
Embodiment 1: a kind of Purple glutinors maize blanching process for cooling, comprises the following steps:
