FD Industrial Freeze-Dryer

FD series from 50kg to 5 tons/day of a single freeze dryer. 10-100 tons/day multiple units. High-quality, high configuration,160W/m-K high efficiency radiant thermal transfer type. Application: food, pets treats, nutraceutical, biological, extract, herbal, coffee, milk and all conceivable kinds.

Why freeze-dry?

Background: to store products, dehydration is required. Other dehydration methods are evaporative drying. The product would be shriveled and collapsed. Poor rehydration performance. The color is dull and far from the original color. Nutrients, biological activity, effective ingredients are seriously lost. The fragrance is disappeared. The storage time is short. But freeze-dry solves all of the above problems!

Freeze drying principle - sublimation: from ice to vapor

In a low-pressure environment, the frozen material is heated to make its moisture directly change from solid ice to gaseous vapor, so as to achieve the purpose of drying the material. No oxidation reaction, no color lost, no shape changing, no aroma and flavor lost, no nutrient loss, no biological activity lost, no effective ingredients lost, longer shelf life.

Specification

FD-series industrial freeze dryer is high-quality freeze-drying equipment; fresh raw product processing capacity of single machines are from 50kg to 5 tons per batch. And the freeze-drying time is shorter compared with other freeze dryers, due to it adopted 160W/m-K high efficiency thermal transfer radiant heating plates and trays. It allows high-quality freeze-dried production based on eutectic point and co-melting point, and ensure no melt-back or collapse of the product; it also allows fast and efficient lyophilization to minimum production cost and maximum profit.

Process of freeze drying:
1, Fresh product pre-processing: peeling, cutting or crushing into pulp.
2, Pre-processed product must be frozen before freeze-drying. In FD-series, it can be frozen in the machine (all-in-one type), or in blast freezer.
3, Freeze-drying: a process of ice sublimation in a vacuum pressure, with refrigeration for vapor condensing and heating for continuous sublimation.
4, Packing the freeze-dried products in a dry room with suitable packing bags.

Application of FD-series:
The FD-series freeze dryer can process any kind of products you can imagine, including food, pets treats, nutraceutical, biological, extract, herbal, oral medicines, except injection and infusion pharmaceutical products.

Freeze-dried input and output:
Fresh product input capacity is loading capacity. Most products can be loaded at their 100% loading ratio, except hallow or sponge light products like scallion, cannabis, flowers. The standard loading ratio is 10 kg/m2 or 10 liter/m2.
The output capacity is various, depending on how many percent of solid matters are there in the fresh product.

Solid matter 15%Solid matter 25%Solid matter 35%Solid matter 45%
Fresh product100%100%100%100%
Dried product15%-18%25%-28%35%-38%45%-48%

Moisture residential in the dried product is less than 1%-3%. Less moisture content in the freeze-dried product, longer shelf life. The price of freeze-dried product decided by the price of raw material, production cost and output percentage.

Features of FD-series:
FD-series is the optimized freeze-drying system based on traditional freeze dryers made of stainless-steel chambers and top brand accessories, with more sizes available. FD-series is widely used in all kinds of industries for thousands of big international companies.

Energy saving:
We offer energy saving options and electricity saving kits for different users whom might really need them, especially in the region where electricity is very expensive. Take FD-500 as an example, the standard installed power is 83kW at 50Hz, and with electricity saving kits, the installed power can be reduced to 42kW, without prolonging the production time. It saved 49.39% by a crazy electricity saving solution.

Efficiency:
Although it saved energy, it still much more efficient in production than traditional contacting freeze dryers. In the case where the sublimation pressure cannot be lowered further, it is especially important to increase the vapor condensation efficiency and increase the heat transfer efficiency. The scientific and reasonable “flow guidance” design and efficient heat transfer in a vacuum environment are all helpful to improve the production efficiency of freeze-drying. This is what we have achieved in the FD series. With specific configurations, to process specific product, a batch of sublimation can be finished within 12 hours, without affecting product quality.

Convenience:
Small and medium size, is integrated structure, all accessories assembled together with freeze dryer chamber, tested before delivery. It’s ready for use, no installation cost. And it is convenient to use. Operators only need to load the product into the machine, and start “Auto Operate” mode, that’s all for today, and come again next day for unloading and packing. Large sized freeze dryers equipped with rail and trolley for fast transporting products from loading area, to blast freezer, chamber, unloading area and packing area. As for large chambers, there will be 2 units of touch screen, one of them are designed at the front chamber near the door. The operators can easily reach it after the door is closed. If the operators do not understand English or Chinese, they may select Spanish or Russian as the first language.

Safety and to operators:
If the operators do not know the technology of freeze-dried, no matter. They may select “Auto Operate” mode; the program will be running automatically. And the operators do not need to worry about the machine status, because there are self-checking and shelf-protecting program in the machine. In case there is a failure, the machine will be stopped for a protection. The operators are free from any risks of explosion, combustion and electric shock. We have more easy-approaching consideration during design, like the height of trays loading, and aisle for operators to walk into.

To technicians:
FD-series have been installed in more than 50 countries, meeting the required installation regulations which covered most of the developed countries. In high-altitude areas, you need to tell us in advance that the machine will be equipped with a motor suitable for high altitudes. Refrigerants are environment friendly types, such as R448A, R449A, R404A, R507A. No damage to the ozone layer, and carbon emissions can meet the relevant standards. To develop new freeze-dried products, you may use both “constant” or “step heating” to make your own recipes, and save the recipes in the system with different names like “Banana Cookie”, “Coffee”, “Yogurt” etc. You can apply patents for your own innovative freeze-dried products. To make sure that the quality of each batch is the same, only the technician can enter the system to set production parameters. And the historical production data and graph picture can be recorded, saved in the system and can be downloaded to your computer for backup.

To director:
We offer mobile phone App monitoring and controlling the equipment as an option. It composed of hardware for data collection from PLC and software to support on the mobile phone App, and the third-party Cloud Server for store and share data in real time. The director or technician can monitor and control the equipment in real time at anywhere. Our 2nd generation mobile phone App monitoring and controlling software can be updated online.
Industrial computer remote control is another option. The third option is to control the equipment on your ERP system in your company by OPC-UA. You can collect production and stock data in real time for easy management, which is suitable for large companies.

FD three main technologies – Refrigeration and Cooling
In FD equipment, both products and cold trap (vapor condenser) need to be cooled with an ultra-low temperature. Freon refrigeration system is the mainstream, and ammonia was widely, and optional nowadays. CO2 refrigeration technology is promising in future. Liquid nitrogen can be used to cool product. It takes few minutes for product cooling only. External cooling for refrigerant by air or water. If the water is hard, a closed cooling tower will be an ideal solution. If the weather is very hot, evaporative cooling tower is an option. Product cooling by in situ freezing or blast freezer, we offer both options.

FD three main technologies – Vacuum
Vacuum is essential for freeze-drying. There is a big amount of vapor sublimated from products. The vapor would cause the increase of pressure. Oil-bathed vacuum pump is not the best choice for freeze-drying application. Oil-free vacuum pump is the best choice. We offer different vacuum solutions for our users.

FD three main technologies – Heating
Heating can be directly by electrical resistance or through liquid to transfer the heat to heating plates. The heat resources can be electricity, steam generated by any types of energy: natural gas, coal, wood, electricity. or solar energy, air energy, or geothermal water or heat recovery from other equipment. Conductive, radiant, far infrared, microwave heat transfer ways are put into practice. The effective ways are adopted.

Wide range of freeze-dry solutions:
1. Lack of funds, trial type, small capacity: HL series
2. Lack of funds and want to build a big factory: EL series
