The invention belongs to the technical field of egg product processing, and particularly relates to a preparation method of low-viscosity high-temperature-resistant egg white liquid. According to the preparation method of the high-temperature-resistant egg white liquid, an interaction mode of egg white components is regulated and controlled through ultrasonic / pH cooperative treatment, so that the heat stability of fresh egg white under the heating condition is improved, and then the high-temperature-resistant egg white liquid is obtained. The method comprises the following steps: carrying out shell-egg separation on an egg to obtain a fresh egg white liquid; treating the fresh egg white liquid by using an ultrasonic pulverizer; adjusting the pH value to 10.6; packaging to obtain a finished product. The finally prepared low-viscosity high-temperature-resistant egg white liquid is still kept in a flowing state after being heated for 5 minutes at 72 DEG C, the turbidity is reduced from 1.87 to 0.38, the protein concentration is increased from 28.9 mg / mL to 96.74 mg / mL, and the gel point is increased from 63 DEG C to 76.5 DEG C. According to the preparation method of the low-viscosity high-temperature-resistant egg white liquid, a theoretical basis is provided for improving the processing applicability of egg white raw materials in downstream industries, and a technical support is provided for development of low-viscosity high-temperature-resistant egg white ingredients.

The invention belongs to the technical field of fruit juice sterilization, and particularly relates to pulsed electric field ultrahigh pressure lemon fruit juice sterilization equipment which comprises a high-pressure vacuum tank, an air outlet is formed in the top of the high-pressure vacuum tank and communicated with a vacuumizing device, a feeding port is formed in the upper portion of the side wall of the high-pressure vacuum tank, and a discharging port and a circulating port are formed in the lower portion of the high-pressure vacuum tank. An electric pulse sterilization device is arranged between the feeding hole and the circulating hole; a filtering device is also arranged below the feeding hole of the high-pressure vacuum tank; a slag outlet is also formed between the feeding hole and the filtering device; a fixed plate is arranged below the filtering device; the high-pressure nozzle is positioned on the fixed lower plate surface and is provided with a downward opening; and a heater is arranged at the bottom of the high-pressure vacuum tank. The sterilization speed is high, the sterilization effect is good, and nutrient substances can be protected in the sterilization process to the maximum extent.

The utility model relates to a drying machine for selenium-rich chicken feed processing, which comprises a drying cylinder, a feeding assembly, a drying assembly and a controller, the feeding assembly is positioned at the top end of the drying cylinder and is used for guiding materials into the drying cylinder, and the drying assembly comprises a plurality of groups of drying units which are axially arranged towards the drying cylinder; each group of drying unit comprises two groups of air outlet pipes oppositely mounted in the drying cylinder and an air heater connected with the air outlet pipes, and the controller is used for controlling the air speed of the air heater. By means of the feed drying device, direct friction and collision between feed and mechanical parts can be effectively avoided, the physical structure and nutritional ingredients of the feed are effectively protected, and the feed drying efficiency is improved. And the product quality is obviously improved. By arranging the three sets of drying assemblies, reasonably controlling the air speed gradient and combining an optimized air outlet structure, accurate drying of feed particles with different weights is achieved, drying uniformity is ensured, and the drying efficiency and the product quality are greatly improved.

This application relates to the field of food processing equipment technology, and in particular to a homogenizing and mixing device for preparing plant protein beverages. The device includes a base plate, a first support fixedly mounted on the top of the base plate, a stirring mechanism mounted on the top of the first support, a vacuum homogenizing mechanism mounted on the top of the stirring mechanism, a shearing mechanism mounted on one side of the vacuum homogenizing mechanism, a pre-mixing mechanism mounted on the top of the shearing mechanism, and a feeding hopper fixedly mounted on the top of the pre-mixing mechanism. Through multi-stage homogenization using small-diameter and ultra-small-diameter homogenizing valves, the slurry particles are significantly refined, improving the uniformity and stability of the beverage and preventing stratification or sedimentation. The vacuum chamber shell and vacuum pump ensure that the homogenization process is carried out in a low-pressure environment, preventing bubble generation and oxidation reactions, and protecting nutrients. A circulating pump and electrically controlled on / off valve enable automated circulation processing, improving production efficiency and meeting different production needs.
