Problems solved by technology

In the current commonly used production process, direct steam injection is mainly used for cooking, and the cooking is realized by heat transfer through direct contact between krill and steam. The heating rate of the material is relatively slow. During the cooking process, the temperature of the material is maintained at about 100°C, and it is difficult to achieve temperature regulation; Separation generally uses a decanter centrifuge for solid-liquid separation, and drying uses steam indirect heating disc drying or drum drying, and the drying temperature is 85-90°C
The traditional shrimp meal processing process has problems such as overcooking, overdrying, low energy utilization rate, juice loss, and large loss of active substances, which affect product quality and yield

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Compared with the prior art, this method increases the process of crushing and solid-liquid mixing, reduces the process of solid-liquid separation, and at the same time innovates the process of key processes such as cooking and drying. The specific implementation process is described in detail as follows:

[0021] S1. Cooking: The cooking process is divided into two stages: the Antarctic krill is placed in the first-stage heating cylinder, and it is rapidly heated to 50-65°C within 2 minutes, and the heating rate is greater than 25°C / min; the material heated by the first stage enters the second stage The heating cylinder can be heated rapidly to 90-100°C, the heating rate is greater than 30°C / min, the heating time is controlled within 2 minutes, and the entire cooking process is controlled within 4 minutes;

[0022] S2. Crushing: the kri...

Abstract

The invention relates to a manufacturing process of euphausia superba powder. The method comprises the following steps: S1. conducting cooking: two stages are in the cooking process: the euphausia superba is transferred to a first-stage heating drum of cooking equipment and is quickly heated to 50 DEG C-65 DEG C within 2 minutes, and the material after heated in a first stage is put into a second-stage heating drum and is quickly heated to 90 DEG C-100 DEG C; S2. conducting crushing: the euphausia superba after second-stage cooking is put into crushing equipment; S3. conducting first-stage drying: the euphausia superba is quickly dried for first-stage drying until the water content of euphausia superba is reduced to 35%-40%; S4. conducting solid-liquid mixing: a cooking liquid obtained from the cooking process is mixed with the material after the first-stage drying, and the water content of the material after mixing is 55%-60%; S5. conducting second-stage drying: the euphausia superbais quickly dried until the water content of euphausia superba is 30%-35%; and S6. conducting third-stage drying. The manufacturing process of the invention adds the steps of crushing and solid-liquidmixing, reduces the step of solid-liquid separation, and at the same time process innovations are carried out in key steps such as cooking and drying.

Description

technical field [0001] The invention relates to a production process of antarctic krill and shrimp powder, which is used for improving the quality and yield of Antarctic krill and shrimp powder, and belongs to the technical field of producing Antarctic krill and shrimp powder. Background technique [0002] Antarctic krill is very rich in resources and is an important part of marine fishery resources. The annual catch can reach 100 million tons, and it is known as the last protein bank on earth. Shrimp meal is the main processed product. [0003] The processing technology of Antarctic krill and shrimp powder is usually: krill→cooking→separation→drying→crushing→shrimp powder. Cooking, separation and drying are the main links that affect the quality and yield of shrimp powder. In the current commonly used production process, direct steam injection is mainly used for cooking, and the cooking is realized by heat transfer through direct contact between krill and steam. The heatin...
