Description

Automatic feeding device for preparing composite spice

Technical Field

The invention relates to the field of automatic feeding devices, in particular to an automatic feeding device for preparing composite spices.

Background

The compound spice is a mixture formed by processing various spices and seasonings such as clove, nutmeg, tsaoko cardamon, star anise, cinnamon, pepper, bay leaf, fennel, cumin pepper and the like into powder and then combining according to a formula, and can be used for adding the flavor and fragrance of food.

The process for preparing the composite spice generally comprises the steps of firstly mixing the prepared spice according to the proportion specified by a formula, then adding the spice into a pulverizer through a hopper, processing the spice into powder by the pulverizer, and fully and uniformly stirring the powder to obtain the composite spice meeting the requirements; during the whole preparation process, the crushing degree and the mixing uniformity degree of the spice can directly influence the taste and the mouthfeel of the final finished product.

In the production process, when mixed spices are added into a pulverizer through a hopper, the shapes, the masses and the volumes of various spices are different, so that the spices with larger particles and the spices with smaller particles are difficult to uniformly distribute in the mixing process, and the final quality of the spices can be influenced by uneven mixing; when the material is fed into the pulverizer through the hopper, the larger spice in the spice can be blocked at the discharge hole of the hopper, so that people are required to manually turn the spice during discharging, the process is increased, and the production efficiency is reduced; meanwhile, when the crushing device crushes some spices with larger volume, such as cinnamon, cardamom, tsaoko and the like, multiple crushing may be needed to achieve proper particle size, which also results in low preparation efficiency.
