KANGBEITE's vacuum freeze drying machines for food are state of the art equipment designed to preserve the nutritional value, flavor, texture, and appearance of various food products through the lyophilization process. The process begins with freezing the food items to sub zero temperatures, typically between 30°C and 50°C, using a powerful refrigeration system. This rapid freezing helps to form small ice crystals, minimizing damage to the food's cellular structure. Once frozen, the chamber is evacuated to a high vacuum level, usually below 10 Pa. Under this low pressure environment, the ice within the food sublimates directly from a solid to a gas, bypassing the liquid phase. This gentle drying process ensures that heat sensitive nutrients, such as vitamins, enzymes, and antioxidants, are retained, and the food maintains its original shape and color. These vacuum freeze drying machines feature high efficiency vacuum pumps, such as rotary vane pumps or oil free diaphragm pumps, to achieve and maintain the required vacuum levels. The drying chambers are constructed from food grade stainless steel, providing excellent corrosion resistance and meeting strict hygiene standards. They can be designed with tray based systems for batch processing, where food is placed on trays that are loaded into the chamber, or continuous conveyor belt systems for high volume production. Advanced temperature control systems, including programmable heating shelves, allow for precise regulation of the drying process, ensuring uniform drying across all products. The machines also come with integrated monitoring and control systems that provide real time data on process parameters like temperature, vacuum pressure, and drying time. This enables operators to optimize the process for different food products, from fruits and vegetables to meats, dairy, and ready to eat meals. With CE certification and comprehensive after sales support, KANGBEITE's vacuum freeze drying machines for food are trusted by food manufacturers worldwide for their ability to produce high quality, long shelf life food products.

Frequently Asked Questions

What’s the average time it takes to dry food?

Warming the moisture out of a particular food will take a certain amount of time based on different variables such as the type of food, initial moisture content, size, or even the temperature settings on the heat drying device. For instance, apples and bananas that are thinly sliced could take anywhere between 6 to 12 hours with a moderate temperature, whereas thick cuts of meat used for jerky could take anywhere between 12 to 24 hours. Vegetables, water-rich like cucumber or tomatoes, would need 8 to 15 hours. Our machines can be customized to suit individual requirements for drying time and speed, and the intelligent control system can make estimates and suggestions based on the food input and the user’s input requirements or aims, thus optimizing time along with the results.
No, it does not. Cleaning and maintaining our food drying machines is very easy considering that they are made with convenience in mind. The removable trays, and drying chambers, as well as other areas within the machine, have smooth surfaces which allow simple wipe cleaning to remove any food residues. Its outer part is made of strong cleanable materials which makes cleaning easy. The bare minimum required maintenance includes removing food after every use, checking or replacing filters where applicable, and sometimes putting grease on the machines moving parts (in certain models). There is no need to worry about instructions since all users are equipped with step by step instructions on cleaning and maintenance through user’s manual. Additionally, our support team is always prepared to assist and will address any questions that the users might have regarding the working order of the machine.
Yes. The food drying machines are designed for industrial production as well as for local bakeries, cafes, and small batch food processing businesses. For commercial applications, we have different models, starting from small units which can handle several kilograms of food to large scale industrial machines which can process hundreds of kilograms per batch. The machines are constructed of reliable components to withstand continuous operation, compliant with all relevant food industry regulations to ensure that the products are safe for sale and consumption. From an established food manufacturer to a nascent food business, our drying machines will serve all.
Certainly, safety is of paramount importance when designing our food drying machines. Each of them has adequate safety measures that will safeguards users while also keeping their food products safe. Protection from overheating ensures that the machine will automatically shut off if the temperature gets too high, which will prevent fires or food spoilage. Also, the machine contains insulation that protects and grounds all of its electrical parts, preventing electric shocks. Additionally, the food drying machines have safety features in the form of locks on the doors or lids to stop accidental opening of the machines while they are working. The locks help to ensure that no hot food or air escapes from the machines. Other users can also take advantage of special emergency stop buttons, enabling them to instantly switch off the machine as needed. All of the features effectively work together with the others to guarantee that food drying is done without any threats.

Transformative for Our Small-Scale Business

The food drying machine has been a transformative element for our business as a small-scale artisanal food producer. It has helped widen our scope of specialty fruits and herbs that we can dry and sell. Previously, we struggled and spent a lot of time drying our herbs because the process was inconsistent. However, now with this machine we have seen a great improvement. This is because it is able to control temperature very precisely and that helps in retaining flavor and scent of the products. Most of our customers appreciate, and a lot of them have taken interest. The reduction in power consumption has in turn, helped reduce our costs, which is beneficial for a small business like ours. Also the after sales service has been fantastic, with the support team always available to help. With this machine, we are able to change the way we produce our food and that has led to an increase in the number of customers.

Modern Sensor Technology

Modern Sensor Technology

The differences between our food drying machines and others on the market are their state-of-the-art sensor technologies. The sensors are so sensitive that they can determine the drying environment and temperature brackets in real time. As a result, heating and airflow is adjusted automatically to be optimal for the food being processed. For instance, if one of the sensors indicates that a food item's moisture content is rapidly changing, the machine is able to change the drying settings instantly to avoid both over-drying and under drying. This technology helps to maintain high standards to which food drying is done and minimizes manual work needed which improves convenience and efficiency.
Programmable Drying Options

Programmable Drying Options

One of the most prominent features of our food drying machines is the creation of programmable drying options that users can customize. Users can set and save specific drying parameters for various foods which include temperature steps, humidity settings, and the duration of drying. What this means is that once the optimal settings for a specific food item are determined, these settings can be recalled during the subsequent cycles, thereby guaranteeing uniformity in the quality of the product. The customizable drying programs offer flexibility ranging from a specific recipe for dried fruits to a unique process for dehydrating vegetables, giving unmatched customization to food producers and enabling them to customize the drying process to their needs and preferences.
Modular and Space Efficient Design

Modular and Space Efficient Design

The food drying machines are designed with a modular and spatially efficient approach which helps food processing facilities the most. They can be set up in places with space constraints like a small commercial kitchen or even in large industrial plants with tight layout limitations. Moreover, the modular design provides customization and expansion ease. Users can modify components based on changing production requirements by adding or removing drying trays and airflow modules. This modularity simplifies adapting to different production volumes and enhances maintenance and upgrade procedures. Ultimately, the machines can be tailored to the business’s needs over time.
