In the vacuum
freeze dryer, moisture sublimes directly from the solid state to vapor,
thus producing a product with controllable moisture, no need for cooking
or refrigeration. The process is first to freeze the water content in the
ingredients into solid form, and then store in a vacuum sealed space, let
the ice changes to vapor in the closed environment and capture it by
freeze equipment. The process is completed until the ice content drop
below 3 to 5% to reach a higher value. The designed full-liquid type low
temperature control with the vacuum pump is able to generate adequate
energy. The machine also features a heating and cooling media which makes
it convenient to operate. |
True-ten vacuum
freeze dryer is especially effective for heat sensitive materials and
allows for closed system benefits. Products made by our equipment will
preserve purity and enzyme activity, maximize nutrient retention, and not
spoil color or other aesthetic characteristics are
maintained. |
