Description

Method and device for preparing bone-clearing concentrated juice/paste from ox stick bone

Technical Field

The invention belongs to the technical field of food production, and relates to a method and a device for preparing bone-clearing concentrated juice (paste) from ox stick bone.

Background

The Lanzhou beef noodles are innovative and developed in nearly one hundred years, not only become a representative of special catering in Lanzhou, but also are a city business card in Lanzhou. The famous snacks "Jinding prize", "Islamic famous food" and "Chinese snacks prize" are successively honored as "the first face of Chinese".

Lanzhou statistics yearbook discovers that the entire city is provided with 1099 Lanzhou beef noodle operating shops at present, the Lanzhou beef noodle operating shops are distributed in five regions of three counties and five districts within the jurisdiction of the entire city, the number of practitioners reaches 1 million persons, the annual business volume breaks through 10 million yuan, and about 70 million persons enjoy beef noodles every day. There are more than 5 million beef noodle houses in Lanzhou around the country, 56 million practitioners, and the annual business amount is nearly 166 million yuan. The Lanzhou beef noodle industry gradually enters a new development stage of upgrading and updating, and the brands universally accepted by the majority of citizens, such as gold tripod, country occupation, Mazilu, Anpoer and the like are successively developed. The development of beef noodles drives the development of peripheral industries (such as beef noodle bowl cleaning and disinfecting companies, paper towel manufacturing companies and vegetable seasoning markets), and meanwhile, employment opportunities are increased, and the employment rate is improved. At present, 15 disinfection bowl companies 30 production lines are shared in Gansu province, about 20 thousands of disinfection bowls are treated every day, and income of nearly 1000 ten thousand yuan is created every year.

By no means, there are relatively few beef noodle houses that are truly operated by Lanzhou. For example, in Shanghai City, 70% of the stores are operated by Qinghai and 20% by Henan. And the noodle shop operated by Qinghai people is in an increasing situation.

Lanzhou beef noodles are produced in Lanzhou, the taste of the beef noodles is easy to change, the main reason is the soup of the beef noodles, and the soup of many foreign beef noodle shops is blended by various seasonings instead of being boiled by fresh beef stick bones, so that how to produce related beef bone soup/paste products to improve the taste of the foreign beef noodles is a problem with market value.

The existing beef noodle soup is prepared by boiling fresh bones in a traditional pot or blending the fresh bones with various seasonings, the beef noodle soup tastes different, collagen in the fresh bones is greatly wasted, and meanwhile, the production capacity is not high, and the beef noodle soup can only be used in a shop.
