Problems solved by technology

[0003] However, the current sandware is only suitable for cooking methods such as boiling, stewing, and steaming. These cooking methods are protected by a large amount of soup water, and the pot is heated more evenly and the temperature difference is small. Therefore, the thermal stability of the pot is relatively strict. Be looser. If you need to use frying, frying, deep-frying and other heating methods with high temperature, rapid fire, and large temperature difference, the existing cooking utensils made of sandware are very prone to bursting.
In addition, if the size of the product is large, it is not easy to produce and process

Abstract

The invention discloses a black sand device and a preparation method thereof. The black sand device is prepared from the following raw materials in parts by weight: 50-80 parts of kaolin and 20-50 parts of carbon slag, wherein the mass percent of iron in the kaolin is 3-5%. }The preparation method comprises the following steps: pulping; forming; airing a billet; firing; glazing; and discharging. The obtained black sand device has specific black gloss, can not be oxidized, can not discolor and has firm texture. Experiments show that the black sand device has higher thermal stability and high temperature resistance, also has corrosion resistance, is harmless to human bodies, and is very suitable for cooking food in daily life.

Description

technical field [0001] The invention relates to the technical field of sand ware and production technology, in particular to a black sand ware and a preparation method thereof. Background technique [0002] The cooking utensils made of sandware are very popular in the common people and the catering industry because of their unique advantages such as good heat storage, environmental protection, and corrosion resistance. For example, the casserole series that appeared on the market are very popular among people. [0003] However, the current sandware is only suitable for cooking methods such as boiling, stewing, and steaming. These cooking methods are protected by a large amount of soup water, and the pot is heated more evenly and the temperature difference is small. Therefore, the thermal stability of the pot is relatively strict. Looser, if it is necessary to adopt high temperature, rapid fire, and large temperature difference heating methods such as frying, frying, and fryi...
