Problems solved by technology

[0003] At present, the processing process of broccoli superfine powder is mainly to dehydrate and dry fresh broccoli, then superfinely pulverize it into superfine powder, and use it as beverage brewing and food and beverage raw materials. The processing technology is: fresh broccoli→cleaning→cutting Ding → high temperature hot air drying and dehydration → superfine grinding → screening → packaging → irradiation sterilization → labeling → finished product However, the current product processing technology has the following defects: fresh broccoli dehydration is dehydrated by high temperature drying, for The color and aroma of the product are greatly damaged, the c

Example Embodiment

[0030] Example 1:

[0031] A processing technology of broccoli superfine powder, the specific preparation process is as follows:

[0032] In the first step, the fresh broccoli is cleaned and drained by a multi-stage combined washing machine, and then the drained broccoli is cut into uniform small dices of about 10mm, and the dice-shaped broccoli is dried (100℃) Steam, 1-3 minutes), and then sent to the freezing room at -18°C for rapid freezing for 3-5 hours, after freezing, enter the vacuum freezer, after 12-18 hours of freeze-drying, control the entire freeze-drying temperature below 50°C, broccoli The flower moisture can be out of the warehouse when the moisture content is less than 8%;

[0033] In the second step, the lyophilized broccoli is pulverized with an ordinary grinder to a fineness of 40-120 mesh;

[0034] In the third step, the coarse powder after the initial pulverization is sent to the superfine grinding unit for superfine pulverization to obtain a 300-500 mesh fine po...

Example Embodiment

[0037] Example 2:

[0038] Such as Figure 1-3 As shown, the multi-stage combined cleaning machine includes a support plate 1. The bottom of the support plate 1 is provided with a dip tank 11, a rinse and drain tank 12, and a discharge buffer plate 13 from left to right; the side walls of the support plate 1 are respectively provided There are a high-pressure washing gun and a drying fan. The high-pressure washing gun and the drying fan are respectively located on both sides of the upper part of the washing and draining tank 12, and the high-pressure washing gun is located on the side of the soaking tank 11.

[0039] The bottom of the flushing and draining tank 12 is located above the bottom of the soaking tank 11. At the same time, the bottom of the flushing and draining tank 12 is located between the soaking tanks 11 and there is a water outlet, and there is a water valve at the outlet, because the dipping tank is for preliminary cleaning , The water is easy to get dirty, the wa...

Abstract

The invention discloses a processing technology of broccoli superfine powder, comprising the following specific preparation processes: cleaning fresh broccoli through a multi-stage combined cleaning machine, draining, dicing, deactivating enzymes, feeding into a freezing room of minus 18 DEG C, quickly freezing for 3-5 hours, feeding into a vacuum freezing bin after freezing, freeze-drying for 12-18 hours, controlling the freeze-drying temperature in the whole process to be below 50 DEG C, and discharging the broccoli out of the bin when the water content of broccoli is below 8%; carrying outsuperfine grinding on the freeze-dried broccoli by virtue of a primary grinding and superfine grinding unit, carrying out UHT sterilization on broccoli superfine powder in a powder sterilization machine system, and then screening, packaging, boxing and labeling the sterilized broccoli superfine powder so as to obtain a finished product. According to the method, fresh broccoli is subjected to deactivation of enzymes and vacuum freeze drying dehydration, the whole dehydration process is in an anaerobic low-temperature process, the broccoli is barely not discolored, the fragrance is not lost, thetaste is kept fresh, and compared with hot air high-temperature drying dehydration, the product quality is greatly improved.

Description

technical field [0001] The invention belongs to the field of broccoli superfine powder preparation and relates to a processing technology of broccoli superfine powder. Background technique [0002] Broccoli, also known as broccoli, broccoli, and green cauliflower, is a variety of Brassica cabbage species that uses green curds as products. The average nutritional value and disease prevention effect of broccoli far exceed other vegetables, and it is known as the "king of vegetables". The nutrients in broccoli are not only high in content, but also very comprehensive, mainly including protein, carbohydrates, fat, minerals, vitamin C and carotene. According to analysis, the protein content of every 100 grams of fresh broccoli is 3 times that of cauliflower and 4 times that of tomato. In addition, broccoli has more comprehensive mineral components than other vegetables, and is rich in calcium, phosphorus, iron, potassium, zinc, and manganese. [0003] At present, the processin...
