Preparation process and device of low-ash pig plasma protein powder

Abstract

The invention discloses a preparation process and device of low-ash pig plasma protein powder. The preparation process comprises the following steps of S01, carrying out centrifugal separation on pigblood by using a first-stage centrifugal machine; S02, carrying out plasma separation on the pig blood subjected to centrifugal separation by using a separator; S03, carrying out sufficient centrifugal separation on plasma by using a second-stage centrifugal machine; S04, carrying out low-temperature heating on the plasma subjected to sufficient centrifugal separation, and carrying out ultrafiltration concentration on the plasma subjected to low-temperature heating; S05, carrying out spray drying on the plasma subjected to ultrafiltration concentration; S06, keeping the plasma powder subjectedto spray drying dry; and S07, carrying out chromaticity vibration screening on the protein powder subjected to dry keeping, so that the chromaticity of the protein powder is kept on a standard line.According to the preparation process and device, the plasma protein can be fully separated from the blood through first-stage centrifugal separation, separation with the separator and second-stage centrifugal separation, the purity of the plasma protein can be fully improved through ultrafiltration concentration, the gray scale of the plasma protein powder is reduced, and the plasma protein powdercan be made to be in a uniform powder shape through spray drying.

Description

technical field [0001] The invention belongs to the field of biological resource production, and in particular relates to a preparation process and a device for low-ash porcine plasma protein powder. Background technique [0002] Pig blood protein powder is a new type of biological protein material produced by the utilization of blood resources in modern society. The production of plasma protein in China is at the middle level in the world, and plasma protein cannot be well utilized. There are also big flaws in the processing and production. For example, the processing of plasma is dried whole blood, which has large nutritional deficiencies, and a large amount of anticoagulant is added to prevent blood coagulation in the collection of raw materials, resulting in high ash content in plasma protein powder. The protein content is low, the solubility is not good, the overall quality is not high, especially the color of plasma protein cannot reach the normal standard, which great...

[0002] Pig blood protein powder is a new type of biological protein material produced by the utilization of blood resources in modern society. The production of plasma protein in China is at the middle level in the world, and plasma protein cannot be well utilized. There are also big flaws in the processing and production. For example, the processing of plasma is dried whole blood, which has large nutritional deficiencies, and a large amount of anticoagulant is added to prevent blood coagulation in the collection of raw materials, resulting in high ash content in plasma protein powder. The protein content is low, the solubility is not good, the overall quality is not high, especially the color of plasma protein cannot reach the normal standard, which greatly reduces the scope of use of plasma protein, which is a waste of huge domestic pig blood resources, resulting in Therefore, in order to solve the above problems, we provide a low-ash porcine plasma protein powder preparation process and its device
