Embodiment 1

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

[0032] In the first step, the fresh broccoli is cleaned and drained by a multi-stage combined cleaning machine, and then the drained broccoli is cut into uniform small dices of about 10 mm, and the diced broccoli is deenzymed (100° C. Steam, 1-3 minutes), and then sent to -18°C freezer for 3-5 hours, after freezing, into the vacuum freezer, after 12-18 hours of freeze-drying, control the freeze-drying temperature of the whole process below 50°C, blueberries The flower water can be out of the warehouse if the water content is below 8%;

[0033] In the second step, the freeze-dried broccoli is initially crushed to a fineness of 40-120 mesh by an ordinary pulverizer;

[0034] In the third step, the coarse powder after primary crushing is sent to the superfine pulverization unit for superfine pulverization to obtain 300-500 mesh fine powder products;

[0035] The fo...

Embodiment 2

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

[0039] The bottom of the rinsing and draining tank 12 is located above the bottom of the immersion tank 11, and the bottom of the rinsing and draining tank 12 is located between the immersion tanks 11 and is provided with a water outlet. The water outlet is provided with a water valve. , the water is easy to get dirty, and the water in the washing and draining po...

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...
