How to Make Freeze Dried Food

Many people know what freeze dried food is now, but not everyone knows how to make it. Maybe so many people like to know how to make it at home, so that they could save the costs and eat any kind of freeze dried food easily. But, in fact, it’s really impossible to do it, since the machine itself is very expensive. You could Google it to find out how much the freeze drying machine is.

Let’s see the procedures of making freeze dried fruit in factory first. At the beginning, we need to buy fruits from some raw material bases we have or buy from other farms. So, no matter what kind of raw materials we all could offer, organic or common one. Then, we begin to pretreat those fruits, selection, cleaning, trimming (if needed), accelerate the ripening (if needed), etc. After that, we get the finest raw materials. Then, go to de-enzyme and cooling. After all this, we will cut those fruits according the requirements, placing in the trays. Then, they would be sent to freeze in low temperature, then go to freeze drying machine. In this process, the moisture in the fruit become ice blocks which would be sublimated in the vacuum chamber to be dried, which is so called freeze dried. After that, those freeze-dried materials would be selected and go through metal detector before packing and sealing to the final product. Is it so complicated? Yes, it’s a little hard to be clear about it at first to me too. This freeze drying technology could protect the color, shape, flavor, taste and nutrition of fruit itself.

By now, we know how the freeze dried food is produced, which is not so magic if we know its real processes and principles. However, it also tells that it’s not easy to freeze dry food at home by ourselves, because we at least need the main freeze dry machines to sublimate the food, which is the key part indeed. You could buy small machine at home, but it will cost so much at first! Then, you will feel that it’s not worthy to buy it, because you will feel so trouble to do it all the time at home. Or if you won’t do it frequently, it’s really no need to buy it. So, why not to buy from our freeze dried food company directly?
