What is a Harvest Right Freeze Dryer?

A Harvest Right freeze-dryer is a specialized machine that preserves food by removing moisture through freeze-drying. This method freezes food and then applies a vacuum to sublimate ice directly into vapor without thawing, preserving flavor, color, texture, and nutrition.

Harvest Right freeze dryers are versatile, allowing you to freeze dry a variety of foods, , including fruits, vegetables, meats, dairy, eggs, and even complete meals like casseroles or stews. Unlike other preservation methods like dehydrating or canning, freeze-drying retains up to 97% of a food's nutrients!

One of the key benefits of these vacuum pump freeze dryers is the longevity of the preserved food. When stored properly, freeze-dried food can last up to 25 years, greatly exceeding the shelf life of other preservation methods like refrigeration or canning. This long shelf life reduces the need for frequent stock rotation. Check some of the prices of freeze dryers in our collection.

Harvest Right freeze dryers offer three types of vacuum pumps: oil, premier, and oil-free. Each pump type has unique features, but all support the efficiency and effectiveness of the machine's operation. Managing the vacuum pump oil keeps your freeze dryer running seamlessly.

Why do freeze dryers need oil?

As we shared earlier, freeze dryers require oil for the vacuum pumps to function efficiently. The oil performs three critical functions: lubrication, cooling, and sealing.

Lubrication

Vacuum pumps in freeze dryers rely on oil to minimize friction between moving parts. Without proper lubrication, internal components experience wear and tear, reducing the life span of the pumps. 

Cooling

The oil cools the vacuum pump. It dissipates heat generated during operation and prevents overheating, which could compromise the freeze dryer’s performance in the long run. 

Seals the Vacuum System 

Oil forms a barrier within the vacuum pump to prevent air from leaking into the system. This seal ensures that air cannot penetrate through your oil and fixtures. Also, while you are at it, check Harvest Right Freeze Dryer variety at our store.
