Description

Material processing method and equipment for super-concentrated hot pot base food

technical field

The invention relates to the field of hot pot base food processing, in particular to a material processing method and equipment for super-concentrated hot pot base food.

Background technique

Chongqing hot pot has the characteristics of various dishes and unique seasoning, so it is very popular among people. However, it is relatively inconvenient to eat. In order to eat hot pot once, it is necessary to go to a hot pot restaurant to experience it. This not only wastes time and money, but also worries that hygiene and taste cannot meet their own requirements. For this reason, the chafing dish bottom material that packs into bag arises at the historic moment. In this way, when people want to eat hot pot, they only need to buy hot pot bottom material, cooking materials and dishes to cook the pot by themselves.

At present, the bagged hot pot base food in the catering industry is basically crushed chili, watercress, Chinese prickly ash, ginger, garlic, various spices and other raw materials, mixed with high fats such as butter and palm oil to form materials, and then boiled at high temperature After cooling, it is packaged together with materials and juice into bags of hot pot base food for sale. Its basic process is: frying or boiling the materials, then filling and cooling together with the materials and juice, and then packaging to obtain the finished product. It is not difficult to see from the above product composition and processing equipment that there are certain defects in this kind of hot pot base food:

(1) The existing bagged products of hot pot bottom material are mainly made of simply crushed chili, Chinese prickly ash, watercress, tempeh, spices and other spices mixed with chicken essence and monosodium glutamate, and fried in oil, because the spices are simply crushed , when adding soup to boil the base soup or cooking dishes, there will be a large number of spice residues, resulting in the residue of spices attached to the boiled or cooked dishes, making it difficult for some people to accept, affecting the taste and sensory quality of dishes and because of the simple pulverization, the crushed spicy raw materials have larger granules, and the fragrance release is slower when boiling, and it takes a long time to boil the fragrance to release, which has a strong impact on the taste of scalding or cooking dishes.

(2) Chicken essence and monosodium glutamate are usually used as umami agents in the existing bagged hot pot bottom ingredients, but the umami taste will be lost during the long-term high-temperature cooking process of monosodium glutamate and chicken essence, which will cause the freshness of the bottom soup to decrease. decline. Therefore, how to keep the freshness of the hot pot bottom material in the high-temperature boiling process is also a difficult point of the hot pot bottom material product.

(3) In addition to the spicy raw materials, the existing bagged hot pot bottoms also contain a large amount of oil and other juices. The amount of water added during cooking is usually 5 times that of the bagged hot pot bottoms. In the storage and transportation process of this bagged hot pot bottom material, once the packaging bag is broken, the juice will flow out and cause pollution, which is extremely inconvenient to carry.

In view of the above reasons, the applicant company has developed a new type of hot pot bottom material that overcomes the above-mentioned defects on the basis of the traditional hot pot bottom material. There is no juice in the bag after the hot pot bottom material is packaged. Up to 10-25 times, so it is named super-concentrated hot pot bottom material. The main ingredients of the super-concentrated hot pot base are shortening, fine chili noodles, Pixian watercress, fermented soybean powder, vegetable protein powder, ginger, garlic, spices and essential oils, food spices, etc., which are processed to form a fragrance that releases when boiled. Fast, there is no spice residue, and the hot pot base will not leak out when the packaging bag is broken. This is a product completely different from the existing bagged hot pot base. The existing production process and equipment of the traditional bagged hot pot base can no longer meet the production requirements of super-concentrated hot pot base, and a new production process is required. And production equipment, in order to meet the demand for the production of super-concentrated hot pot bottom material.
