Description

Technical Field

[0001] The present invention relates to the technical field of condiment processing, and particularly to a grinding and screening machine for solid condiment processing. Background Art

[0002] Condiments mainly refer to herbs and spices. Herbs are the leaves of various plants. They can be fresh, dried or ground. In some cases, a single plant can be used to produce both herbs and spices. Some condiments are a mixture of multiple spices (such as paprika), or a mixture of multiple herbs (such as a sachet of spices). Products that are widely used in diet, cooking and food processing to improve the taste of food and have functions such as removing fishy smell, mutton smell, greasiness, enhancing fragrance and freshness.

[0003] The grinding of spices required for solid condiment processing is usually carried out using a small steel mill. The grinding and screening are achieved through the rotating chopping knife and filter screen inside the small steel mill. Subsequently, a screening machine is used to screen out finer spice powders. The entire process of obtaining the spice powders requires switching between two devices, resulting in low efficiency. For this reason, we propose a grinding and screening machine for solid condiment processing. Summary of the Invention
