Abstract
Description
Technical Field
[0001] This patent relates to the technical field of raw bird's nests, edible bird's nests and their processed products, specifically a non-immersion bird's nest nitrite removal box. Background Art
[0002] With the improvement of people's living standards, bird's nest has become the choice of more and more consumers for daily health care and festival gifts. Bird's nests are divided into house bird's nests and cave bird's nests according to their sources. House bird's nests are produced from bird's nests built by humans, and cave bird's nests are produced in caves on islands or by the sea. The raw material of unprocessed bird's nests is called raw bird's nests. The bird's nests made by sorting, cleaning, picking hair, drying and other processes are called edible bird's nests. According to the processed form, they are divided into bird's nests (divided into official nests and corner nests), bird's nest strips and bird's nest pieces, and the appearance also declines. Due to the breeding and management tradition of house bird's nests, in order to attract swiftlets to build nests in the bird's house, the feces accumulated in the bird's nest are generally not cleaned. The interior of the bird's house is damp, opaque, and air circulation is poor all year round. The feces and uric acid excreted by the swiftlet are very easy to produce nitrite and nitrate under the action of microorganisms;
[0003] The current treatment methods mainly include washing, oxidation, adding nitrite formation inhibitors, and microbial methods such as yeast to remove nitrite. Although the method of using ozone and hydrogen peroxide oxidation can remove nitrite, there is a situation where bird's nests with high nitrite content are discolored (bird's nests with high nitrite content appear yellow), and there is a hidden danger of bleaching during the hair removal process of raw bird's nests. At present, the removal of nitrite from bird's nests requires mixing with water and soaking. This method increases the actual manual operation of bird's nests, which not only reduces labor efficiency, but also causes the loss of nutrients, especially sialic acid and other substances due to water soaking. Therefore, the existing technology needs to be improved. Utility Model Content

[0040] Working process and principle: When in use, connect the vertical pipe 5 with the connecting pipe 6, and 2 Flow meter 2 and N 2 Aeration pipe N 2 Connect the trachea 3, put the raw bird's nest into the removal box, and pass N 2 After 5 minutes, wet the raw bird's nest with the pre-prepared nitrite reductase liquid, and then maintain positive pressure for more than 5 minutes to remove the nitrite in the raw bird's nest, followed by the dehairing and drying process. The specific process flow is as follows:
[0041] Harvested raw bird's nest → pass 99.999% N into the nitrite removal box 2 5min→Put the raw bird's nest into the nitrite removal box→Pass 99.999% N 2 5min→Spray nitrite reductase liquid on the raw bird's nest and moisten the raw bird's nest→Maintain positive pressure for more than 5 minutes→Take out the raw bird's nest→Manually remove the bird's feathers→Dry in the air or in a oven→Finished product→Packaging;
[0042] Nitrite removal box, open N2 outlet pipe 10, close film sleeve 9, pass nitrogen with a purity of 99.999% from N2 flowmeter at a flow rate of 6L / min, ventilate for 5 minutes, the purpose is to remove the oxygen inside the box; after 5 minutes, open film sleeve 9 and put 12 raw bird's nests, close film sleeve 9, and continue to pass nitrogen for 5 minutes, the purpose is to remove the air brought in; after 5 minutes, open film sleeve 9 and spray nitrite reductase liquid on the surface of raw bird's nest in a spray state until the raw bird's nest is wetted, then close film sleeve, close N2 outlet pipe 10, so that When the pressure gauge value rises to 0.03MPa, the N2 flowmeter is closed and the positive pressure is maintained for more than 5 minutes. The purpose is to allow the nitrite reductase to fully react with the nitrite in the raw bird's nest under anaerobic conditions and decompose the nitrite into ammonia or nitrogen. After reacting for more than 5 minutes, the N2 flowmeter and the N2 outlet pipe 10 are opened in sequence to remove the ammonia and other nitrogen-containing compounds produced. The N2 outlet pipe 10 is closed, the film sleeve 9 is opened, and the raw bird's nest in a wet state is taken out for dehairing. At the same time, the film sleeve 9 is closed to maintain the pressure at 0.03MPa and the N2 flowmeter is closed. After the dehairing of the raw bird's nest is completed, another wetted raw bird's nest is taken out, and a new raw bird's nest waiting to be processed is placed in the box to perform the above-mentioned related operations, thereby realizing continuous operation. Through this operation, the nitrite removal rate reaches more than 92%, and it has the advantages of no loss of nutrients, effective integration with the original process, and the overall operation time is only increased by 15 minutes.
