Description

Technical Field

[0001] The invention relates to the technical field of food additives, and in particular to a low-salt carrageenan production device and method. Background Art

[0002] Carrageenan is a hydrophilic colloid, also known as euchelin gum, agar, carrageenan, and carrageenan, because carrageenan is a hydrophilic colloid extracted from red algae seaweeds such as euchelin, agar, and carrageenan. Its chemical structure is composed of calcium, potassium, sodium, and ammonium salts of polysaccharide sulfates composed of galactose and dehydrated galactose. Due to the different binding forms of sulfates, it can be divided into K type (Kappa), I type (Iota), and L type (Lambda). It is widely used in the manufacture of jelly, ice cream, cakes, soft candy, canned food, meat products, eight-treasure porridge, white fungus and bird's nest, soup foods, cold foods, etc. Carrageenan production needs to go through the steps of raw material processing, extraction, pressing, precipitation, centrifugation, drying, etc. Pressing is to put the carrageenan raw material into the screw press. The screw rotates to gradually reduce the volume of the carrageenan raw material, and the carrageenan raw material is squeezed and dehydrated. If the amount of raw material added increases or the screw speed increases, the raw material pressing pressure will increase. If the pressing pressure exceeds the standard pressure, the carrageenan will deteriorate. Moreover, the mixed liquid after pressing cannot be extracted and separated, resulting in the waste of carrageenan residue and water resources in the mixed liquid. Therefore, it is necessary to propose a low-salt carrageenan production equipment. Summary of the invention

The distilled water flows into the distillation water tank along the distillation tube, and the solid carrageenan residue remains in the separation tank. Therefore, the solid-liquid separation of the carrageenan raw material is achieved, which can prevent the waste of carrageenan and save water resources. 2.

By adjusting the squeezed space between the pressure relief plates, the pressure on the carrageenan raw material is kept constant, preventing the quality of the carrageenan from decreasing due to excessive pressure, and protecting the quality of the carrageenan during squeezing.

[0021] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0022] Step 1: Raw materials are put into the hopper 37 and fall into the filter barrel 32. The screw 35 is driven to rotate by the reducer 34. The screw 35 pushes the raw materials to move to the right along the inner wall of the filter barrel 32. Since the opening of the pressure relief mechanism 5 is small, the raw materials are gradually squeezed in the filter barrel 32. The water and residue squeezed out of the raw materials pass through the mesh of the filter barrel 32 and fall into the collecting tank 7. The squeezed raw materials are squeezed out from the central hole of the pressure relief plate 510 to achieve the squeezing of carrageenan raw materials. Step 2: When the squeezed mixed liquid needs to be separated into solid and liquid, the valve 43 is opened to allow the mixed liquid to flow into the separation tank 41, and the valve 43 is closed. The built-in heater in the separation tank 41 heats the mixed liquid, and the water in the mixed liquid is gradually converted into water vapor. The water vapor moves along the air pipe 442 and the distillation tube 441. Under the influence of the cooling of the distillation tube 441 by the condenser 443, the water vapor releases heat and liquefies to form distilled water. The distilled water flows into the distillation water tank 45 along the inclined surface of the distillation tube 441 to separate the carrageenan residue from the water. Step 3: When it is necessary to release the pressure of the squeezed raw material, once the amount of raw material added is too large or the speed of the screw 35 changes and causes the raw material pressure in the filter cartridge 32 to exceed the standard, the raw material extrusion pressure relief plate 510 deflects to the right, and the sector gear 57 moves the rack 55 to allow the annular plate 54 to move along the left side of the outer wall of the guide rod 52. The space between the pressure relief plates 510 is increased, the amount of raw material extrusion is increased, and the pressure of the raw material is released; When the pressure of the raw material decreases, the elastic force of the spring 53 pushes the annular plate 54 to move rightward, and the pressure relief plate 510 rotates under the transmission of the sector gear 57 and the rack 55, reducing the raw material extrusion space, thereby achieving pressure relief when squeezing the raw material.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
