Product Introduction

Freeze-dried tea powder

The production equipment of instant tea freeze-dried powder mainly includes concentration equipment, freeze-drying machine, etc. The freeze-drying principle of instant tea requires the quality of freeze-dried instant tea as follows: unchanged biological activity, uniform color and color in appearance, full shape, stable structure, fast dissolution and low residual moisture. The freeze-drying process includes four stages: pre-treatment, pre-freezing, sublimation and re-drying.

The preparation method of freeze-dried instant tea powder is as follows: tea → blending → leaching → purification → concentration → prefreezing → freeze-drying → packaging. From the point of view of freeze-drying technology, the process flow of instant tea is analyzed, from tea blending to concentration is the pre-treatment part of freeze-drying technology. To extract as much as possible the original bioactive substances in tea, freeze-dried enrichment process of instant tea is usually used under normal temperature, without phase change, and in the closed system is done in reverse osmosis technology as a means of enrichment, without using high working temperature, phase transformation, system not airtight vacuum enrichment technology, to prevent the influence of temperature and phase change the original quality of tea. It can be considered that reverse osmosis technology is a congruent concentration technology with freeze-drying technology.

Vacuum freeze-drying process is a process of high energy consumption, the freeze-drying of instant tea is actually more similar to the freeze-drying of biological agents. However, the added value of instant tea is much lower than that of medicine, so it is impossible to adopt the freeze-drying method of medicine, so it is advisable to adopt the freeze-drying method of food with lower cost, that is, the new generation of shelf pre-frozen food freeze-drying machine equipment, without cold storage.
