Embodiment 1

[0021] The raw material is fresh hairy crabs with a specification of less than 100 grams. After cleaning, they are directly sent to the conveyor belt and sent to the cooking machine for cooking. The cooking temperature is 120°C, the cooking time is 8.5 minutes, and the center temperature of the hairy crab body is ≥75°C. The steamed hairy crabs are directly transferred from the normal temperature water cooling tank to the conveyor belt of the cooling water cooling tank, the cooling water temperature is 0°C, and the center temperature of the hairy crab body is controlled below 10°C. The cooled hairy crabs are graded, and then weighed and placed on a plate. The hairy crabs that have been placed on the plate are wrapped in sterilized packaging bags, and then the soup is automatically added with a soup gun, and then vacuum-sealed after adding the soup. Use a liquid nitrogen quick-freezing machine for quick-freezing, place the hairy crabs individually on the conveyor belt, and freez...

Abstract

The invention discloses a processing method of frozen cooked clear-water hairy crabs and belongs to the technical field of aquatic product processing and preservation. According to the invention, the frozen cooked clean-water full-body hairy crab products are prepared by adopting fresh and live hairy crabs as raw materials through the steps of performing selection, performing rinsing, performing cooking, performing cooling, performing grading, performing measuring, performing placing onto dishes, performing soup juice addition, performing vacuum packaging, performing quick-freezing, performing metal detection, performing outer packaging and performing refrigeration. According to the invention, the effects are as follows: the originally contained flavors and nutrients of the hairy crabs are effectively retained through high-temperature fast cooking and a liquid-nitrogen flash freezing technology; the limits of regions and seasons are eliminated; and a sales radius is expanded.

Description

technical field [0001] The invention provides a method for processing frozen and boiled hairy crabs in clear water, which belongs to the technical field of aquatic product processing and preservation. Background technique [0002] Chinese mitten crab is a kind of economic crab, also known as river crab, hairy crab, clear water crab, and hairy crab. It is an aquatic product with high economic value in my country. Crabs have the effects of clearing heat and detoxifying, nourishing bones and marrow, nourishing tendons and activating blood circulation, dredging meridians, sharpening limbs, healing wounds, nourishing liver yin, and filling gastric juice. Crab meat and crab roe contain essential amino acids, trace elements, collagen, calcium, lecithin, vitamins and other nutrients, which are deeply loved by consumers. According to statistics, in 2014, the national production of hairy crabs exceeded 700,000 tons, of which Jiangsu, Anhui and Hubei are the main producing areas. How...
