Problems solved by technology

[0003] At present, the traditional apple processing technology directly squeezes the apples after they are crushed to separate the fruit juice and pomace. This process has many disadvantages, such as browning of the fruit juice and large amount of pesticide residues. For the concentrated clear apple juice, there are The problem of over-processing, quality decline, and nutrient content reduction are mainly manifested in high levels of hydroxymethylfurfural and low levels of apple polyphenols and phloretin; in addition, the processing depth of apple resources is insufficient, which easily leads to waste of resources

Embodiment 1

[0043] see figure 1 , the apple processing method based on the separation before pressing of the present embodiment comprises the following implementation steps:

[0044] Step 1: crushing and centrifugal separation, specifically:

[0045] Step 1.1: Put 10000Kg of cleaned and picked apples into the feeding hopper of the fruit and vegetable cold crushing separator, and enter the crushing system under the push of the feeding auger. Cut into pieces in the gap with the broken screen;

[0046] Step 1.2: The apple fragments enter the separation system under the push of the subsequent incoming materials, and the separation dial is driven by the transmission device to rotate at a high speed, driving the apple fragments to move along the gap between the crushing dial and the separation screen, and the 3mm screen intercepts the flow Under the effect, obtain 400Kg pericarp seed component and 9600Kg pulp pulp component.

[0047] Step 2: Dry pressing is specifically:

[0048] The 400Kg ...

Abstract

The invention belongs to the technical field of food and particularly relates to an apple processing method based on separation before squeezing. The method comprises the following steps that:1) crushed apples are subjected to centrifugal separation, and pulp and flesh are separated from peel and seeds through screen intercepting; 2) the peel and the seeds are subjected to microwave drying treatment, the pulp and the flesh ingredients are subjected to squeezing treatment, and juice and flesh crude slag are separated out; 3) the dried peel and seeds are subjected to cyclone separation, the peel and the seeds are separated, the separation rate reaches 95 percent, the flesh crude slag is subjected to digestion for ten minutes by distilled water with the mass ratio being 1:1 at 70 to 80 DEG C, the secondary squeezing is carried out, and the juice and the flesh slag are separated for a second time. The fruit processing method has the advantages that the flesh, the pulp, the peel and the seed ingredients are respectively finely separated, the peel, the seeds, the juice and the flesh slag are separated, different processes are adopted, the resource utilization of the flesh, the peel and the seeds is realized, production groups with various nutrition functions are formed, and the clean production and energy-saving and emission-reduction level of the fruit processing enterprises is improved.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to an apple processing method based on a refined separation process of apples before pressing. technical background [0002] Apples are rich in nutritional value. Chinese medicine believes that apples have the effects of promoting body fluid, nourishing the lungs, relieving restlessness and heat, appetizing and sobering up, and stopping diarrhea. Modern medicine believes that it has a certain effect on the prevention and treatment of hypertension. Apples contain "apple polyphenols". "Apple polyphenols" have antioxidant effects, which can keep food fresh; eliminate peculiar smell, remove fishy smell and bad breath; prevent tooth decay; Prevent various lifestyle-related diseases caused by active oxygen; suppress blood pressure rise, prevent high blood pressure; suppress allergic reactions. Apples also contain "pectin", which can reduce the number of bad bacteria in the int...
