Description

TECHNICAL FIELD

[0001] The utility model relates to food engineering technical field, especially a kind of feeding system for pea protein production. BACKGROUND

[0002] Pea is an important dietary legume resource, which contains rich starch and pea protein. The pea protein extracted therefrom has consistent amino acid composition with the recommended value of FAO / WHO, and is a high-quality plant protein.

[0003] Currently, the main production method of edible pea protein is wet processing method, i.e. alkali dissolution and acid precipitation method. The basic process is as follows: 1) dry peas are color-selected, impurity-removed and crushed, and then adjusted into pea powder slurry by adding water; 2) alkali is added to the pea powder slurry to make the pH value of the solution between 9.5-10.5, and the separated starch and fiber are separated by a horizontal screw separator; 3) hydrochloric acid is added to the separated protein solution to adjust the pH value of the solution to 4.5, so that the protein flocculates, and the flocculated protein is separated by a horizontal screw separator. The protein enters subsequent neutralization, sterilization, homogenization and drying sections to obtain protein finished product.

[0004] In the industrialized production process of pea protein, in order to pursue stable feeding requirements, one material feeding pump is generally used to feed and convey one horizontal screw separator. When the production amount of protein is large and multiple horizontal screw centrifuges are needed for separation, multiple pumps need to be arranged correspondingly, which requires a higher site. At the same time, when the pump fails, there is no standby pump to feed and convey the horizontal screw separator, which will cause the centrifuge to stop, thereby affecting the service life of the equipment and the yield of the product.

[0013] The preferred technical scheme is that the distributor is an elongated horizontal pressure vessel tank, the bottom of the distributor is equipped with a discharge port, and the discharge port is equipped with a discharge valve to facilitate cleaning of the interior of the distributor.

[0014] The preferred technical scheme is that the solid-liquid separation equipment is a horizontal screw centrifuge, and the separation efficiency is stable.
