Description

A kind of processing equipment and processing technology of Midu rolled hoof

technical field

The invention relates to the technical field of food processing, in particular to a processing equipment and a processing technology for Midu rolled hoof.

Background technique

The food industry has become the third pillar industry of China's real economy and occupies an important position in the national economy. With the development of science and technology and the expansion of trade, my country's meat industry has developed rapidly. The proportion of animal protein in people's daily food intake is getting higher and higher, and the nutritional level has been greatly improved. Today's market requirements for food are no longer limited to deliciousness, belly-packing, and high cost performance, but further extend to food safety, nutrition, and even functional health food. China is the largest meat producer and consumer in the world, but for a long time, there have been problems in the production process, such as poor sanitation, low level of industrialization, single product variety, and simple processing equipment, making it difficult to achieve large-scale production.

Rolled hoof is a traditional food of ethnic minorities in Yunnan. It is popular among local people of all ethnic groups because of its delicious color, various eating methods, and easy storage. Among them, the one made in Midu County is the most famous, so it is also called "Midu Rolling Hoof". Rolled trotters are not pig trotters, but a cured meat product shaped like pig trotters. In the past, most people used to eat Midu rolled trotters as a cold product, which is one of the reasons why Midu rolled trotters are famous. But now there are also people who eat Midu Rolled Hoof in other cooking methods, and it is also very delicious. Due to the low degree of automation, the existing Midu roll hoof is purely manual production, and the production efficiency is too low, so that the main production and consumption of Midu roll hoof currently comes from the local Midu and surrounding counties and cities.
