As you might have seen on the official website of Shandong Joyang Machinery Co., Ltd., our food extruder and industrial microwave equipment are widely used in a variety of food production, such as puffed food, beverages, porridge powder, fruits and vegetables, medicine, pet food, etc. Facing the global market, different manufacturers have put forward higher requirements for the processing technology of the above products. In line with the purpose of being closer to the needs of users, Joyang company has provided more and more users with the solution of vacuum freeze dryer. Our vacuum freeze dryer solves the problems that cannot be solved by conventional drying or puffing technology, and improves the quality of processed products by leaps and bounds.


Below we focus on a brief description of the most widely used food freeze-drying technology, hoping to inspire and help you:

A. Why do we use vacuum freeze-drying&dehydration technology to process some specific foods? The main reasons are as follows:


1. Keep the food structure, nutrients and flavors basically unchanged, especially the highest retention rate of physiologically active ingredients, which is the main reason why some functional foods use freeze-dried food as the base material.


2. The appearance of freeze dried product does not crack or shrink, and maintains the original shape, color, and teste of the food;


3. The product has no surface hardening, and the tissue is porous sponge-like, so the rehydration performance is good, it is convenient to eat. Freeze dried product can be restored by soaking, thus determining its position in the instant convenience food;


4. The freeze dried product is light in weight, resistant to storage, and has no special requirements for ambient temperature. When protected from light and vacuumed and filled with nitrogen, it can be kept for about 2 years under normal temperature conditions. The recurring costs such as storage, transportation, and sales are much lower than frozen food.


B. What products can be processed by the vacuum freeze dryer of Joyang Company?


As long as the water content does not exceed 85%, non-toxic and non-corrosive substances, the products can be dried with freeze-drying technology. Almost all agricultural and sideline products, such as meat, poultry, eggs, aquatic products, vegetables, fruits, etc., can be made into freeze-dried food, condiments, instant food, etc.
