Description

Aquatic product precooling and cleaning device

Technical Field

The utility model relates to a belt cleaning device, in particular to aquatic products wash and precooling apparatus.

Background

In recent years, people have higher and higher requirements on food, particularly the freshness of aquatic products, so that in order to enable ordinary people to eat fresh fish food, the state vigorously develops a freezing technology and a cold chain transportation technology.

The cold chain refers to a special supply chain system which is used for reducing loss, preventing pollution and deterioration and ensuring the food safety, biological safety and medicine safety of products after certain food raw materials, processed foods or semi-finished products, special biological products and medicines are purchased, processed and inactivated and are always in a special low-temperature environment required by the products in the processes of processing, storing, transporting, distributing, retailing and using the products.

Therefore, in consideration of economic benefit, the transportation of aquatic products is dependent on a cold chain, so that the aquatic products need to be refrigerated. The low temperature condition is utilized to inhibit the activity of autolytic enzyme and the propagation of attached microorganism, and slow down the chemical reaction speed of lipid oxidation, non-enzymatic browning and the like, so that the water product can keep excellent quality during storage.

However, direct freezing can destroy the microstructure of aquatic products, destroy the cell tissues of foods, and lose the juice of the thawed foods, which has a great influence on the taste.

And traditional aquatic products are washed by water flow, so that the aquatic products are not easy to clean and waste water resources greatly.

the ultrasound can strengthen the heat transfer in the freezing process, promote the ice crystallization in the food freezing process, improve the quality of the frozen food and the like. The ultrasonic wave can promote the nucleation of ice crystal and inhibit the growth of crystal.

The ultrasonic wave has a good cleaning function, and the cavitation action, the acceleration action and the direct current action of the ultrasonic wave in the liquid are utilized to directly and indirectly act on the liquid and dirt, so that the dirt layer is dispersed, emulsified and stripped to achieve the cleaning purpose.

Therefore, the ultrasonic generator is arranged in the device, aquatic products are cleaned by ultrasonic waves, and water resources can be saved while a good cleaning effect is achieved. In addition, because the water used for cleaning is the brine with the temperature lower than 0 ℃, the temperature of the aquatic products is gradually reduced in the cleaning process to achieve the purpose of precooling, and the freezing effect of the aquatic products is superior in the precooling process due to the improvement effect of the ultrasonic waves on the freezing.

Therefore, the aquatic product cleaned and precooled by the device can achieve a better freezing effect in subsequent freezing, and the flavor of the aquatic product can be better retained.

The terms "mounted", "disposed", "provided", "connected", and "sleeved" are to be construed broadly. For example, it may be a fixed connection, a removable connection, or a unitary construction; can be a mechanical connection, or an electrical connection; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements or components. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Specific example 1:

when the device is used, the water outlet 4 at the fourth tank wall 15 is closed, water is injected into the cleaning tank 1, the temperature of the water is lower than 0 ℃ saline, and aquatic products to be cleaned are poured into the cleaning tank 1 after the saline in the tank reaches a certain degree (the water level needs to submerge the ultrasonic generator 2), wherein fishes are taken as an example.

Adjust the sparse degree of 3 horizontal poles of isolated column for the abluent fish of needs can't pass through isolated column 3, and the fish will stop on isolated column 3 like this. The ultrasonic generator 2 is turned on so that the saline in the cleaning tank 1 is filled with ultrasonic waves.

Since the saline water is filled with the ultrasonic waves, the fishes in the washing tank 1 are sufficiently washed, and the dirt is separated from the fishes. In the cleaning process, the temperature of the saline water is very low, and the temperature of the fishes is reduced under the action of the ultrasonic waves, so that a good precooling effect is formed.

After cleaning and precooling are completed, the ultrasonic generator 2 is closed, standing is carried out to enable dirt to be precipitated into the precipitation cavity 31, and finally the switch mechanism at the water outlet 4 is opened to drain the saline water.

Specific example 2:

on the basis of the specific embodiment 1, as a large amount of aquatic products are required to be cleaned in the actual operation process, the device needs to work continuously, in this case, saline water with the temperature of below 0 ℃ needs to be continuously injected into the cleaning pool, and the water outlet 4 is kept in an open state. The water injection rate needs to keep the low-temperature saline water in the cleaning pool 1 at a certain liquid level height which is higher than that of the ultrasonic generator 2. In the actual operation process, the water outlet 4 is closed firstly, then the water outlet 4 is opened after the liquid level reaches a certain degree, and then the water injection rate is adjusted to ensure that the water injection rate is consistent with the water drainage rate, so that the liquid level of the low-temperature brine is kept balanced.

Continuously throwing aquatic products into the cleaning pool 1 from the slope 11, and continuously taking away dirt on the aquatic products by water flow due to the continuous flow of the water flow in the cleaning pool 1, discharging the aquatic products from the water outlet 4, and fishing out the cleaned aquatic products. Therefore, aquatic products are continuously put into the water tank and continuously fished out, and the cleaning and precooling efficiency is greatly improved.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the inventive concept, and these should also be considered as the protection scope of the present invention.
