The items should be packaged as quickly as possible, ideally within 1 hour, to prevent moisture absorption and maintain their flavor and quality.

Vacuum level (determined by the vacuum pump);
Freezing speed (determined by the compressor);
Leaks (related to mechanical design);
Water capture ability (cold trap).

The typical yield is calculated by multiplying the square footage of the drying chamber by 10-12 times the amount of material in kilograms.

One batch typically takes about 20-22 hours to complete.

The biggest benefit is that the equipment is cost-effective, as it does not require pressure vessels. It is easy to operate, provides fast extraction speeds, and produces products that are more suitable for purification.

The choice between alcohol extraction and water extraction depends on the specific process. Alcohol extraction is generally faster and can be more efficient for certain oils, but it may come with higher costs. However, with the proper process, the final oil will not contain any solvent impurities because an oil-water separator is used to remove any remaining alcohol or water. This ensures that the oil is pure and suitable for use. The cost-effectiveness of either method depends on factors such as raw material, production volume, and the desired quality of the final product.
