Abstract

The invention discloses a novel serial processing method for preparing acorn whole powder. The steps of the serial processing method for the acorn whole powder are as following: sorting: acorns which are even in size, non-moth and un-musty are sorted; crushing: the acorns are put into a crusher to be crushed, generally each acorn is crushed into 4 to 8 segments; edulcoration: the acorns are soaked with water according to the 1:4 ratio of the acorns and the water, cellulase is added, the enzymolysis time is 8 hours, the enzymolysis temperature is 45 DEG C, the enzyme adding amount is 20 EGU/g, and the enzymolysis potential of hydrogen (PH) value is 6.5. Then an ultrasound process is conducted, the time is 50 to 60 minutes, the ultrasonic wave power is 454 watts, the frequency is 47.6KHz, then a bleach washing process is conducted with 2 time amount water, and then the processes of pulping, dehydration, bleaching and edulcoration are conducted. Drying: wet acorn starch is dried through vacuum drying technology and a device, the drying time is 70 to 80 minutes, the vacuum degree is 0.08 to 0.09 MPa, and the temperature is 50 to 60 DEG C. The serial processing method for the acorn whole powder provides a new approach for serail processing of the acorn starch, the processes of starch sun-drying and shell removing used by a normal method to produce acorn starch are eliminated, and the man power and material resources are saved.

Description

The full powder processing method of a kind of serialization acorn nut

Technical field:

The present invention is a kind of complete processing of the novel full powder of preparation acorn nut.

Background technology:

In producing the acorn starch process, at first acorn nut needs to shell, and present exuviating technology and technique need long airing, and the machine shelling exists that husking yield is low, the time is long, problem that can not serialization production

Summary of the invention:

The object of the invention is to overcome the deficiency of the full powder processing of existing acorn nut, the problem that husking yield is low, the time is long, can not serialization produce, propose a kind of with short production cycle, quality product is high, and water consumption is few, wastewater discharge is few, can not cause to environment the full powder processing method of serialization acorn nut of severe contamination.

Realize that the technical scheme that the object of the invention adopts is:

Carry out according to the following steps:

1. select materials: select a grain evenly, without moth, without the acorn nut that goes rotten;

2. pulverize: it is broken that acorn nut is put into pulverizer, the broken 4-8 lobe of general every acorn nut;

3. removal of impurities: acorn nut is soaked than 1: 4 by the material quality, and added cellulase, enzymolysis time 8h, 45 ℃ of hydrolysis temperatures, enzyme concentration 20 EGU/g, enzymolysis pH value 6.5.Then carry out ultrasonicly, time 50-60min, ultrasonic power 454W, frequency 47.6kHz use the water rinse of 2 times of amounts at last, then through making beating, dehydration, rinsing removal of impurities.

4. dry: utilize vacuum drying technique and the device full dried bean noodles of acorn nut that will wet dry, time 70-80min, vacuum tightness 0.08-0.09MPa, temperature 50-60 ℃.Pulverize and sieve and obtain the full powder of pure acorn nut.

The present invention has provided the new way of the full powder of a kind of acorn nut processing, has saved general method and has produced the full powder of acorn nut dry in the air Sai, the process of shelling, and process period is short, can serialization production, saved manpower and materials.

Description of drawings:

Fig. 1 is process flow sheet of the present invention.

Embodiment:

Below in conjunction with drawings and Examples in detail the present invention is described in detail.

3. removal of impurities: chestnut is soaked than 1: 4 by the material quality, and added cellulase, enzymolysis time 8h, 45 ℃ of hydrolysis temperatures, enzyme concentration 20 EGU/g, enzymolysis pH value 6.5.Then carry out ultrasonicly, time 50-60min, ultrasonic power 454W, frequency 47.6kHz use the water rinse of 2 times of amounts at last, then through making beating, dehydration, rinsing removal of impurities.

4. dry: as to utilize vacuum drying technique and the device acorn starch drying that will wet, time 70-80min, vacuum tightness 0.08-0.09MPa, temperature 50-60 ℃.Pulverize and sieve and obtain pure acorn starch.

Claims

1. a novel serialization prepares the complete processing of the full powder of acorn nut, carries out according to the following steps:
