Blanching Machine
A blancher gives raw food a quick dose of heat, either in water or steam. That short hit is blanching. The machine also goes by scalder or pre-cooker. It is used mostly around vegetables and fruit, but meat and seafood get the same treatment when they need it-before freezing, drying, canning, or whatever comes next.
Why is blanching performed using commercial blanching equipment?
01
Polyphenol oxidase is what turns potatoes, fruit, and vegetables brown once they're cut. Blanching knocks it out. On a French fry line, that's the difference between golden strips and ones that go dark in the fryer.
02
Root crops like potatoes and sweet potatoes come out of blanching and rinsing with less surface starch. Without it, they tend to stick together in the fryer and soak up more oil.
03
The raw, grassy notes in vegetables get cooked off, which cleans up the flavour of the finished product.
04
The tissue softens just enough, and its structure sets. You can then fry, quick-freeze, or dehydrate without ending up with mush or something overcooked.
Which food ingredients can be blanched?
Materials it handles
Potatoes cut into strips for fries, plus carrots and sweet potatoes
Edamame, soybeans, peanuts
Broccoli, green beans, okra, spinach
Shiitake and enoki mushrooms, along with other fungi
What are the main types of machines?
Commercial blanching equipment is divided into two main categories based on modes of operation: continuous-type (fit for large plantations, continuous production; higher initial investment) and batch type (small-batch, multi-variety production; better price-performance ratio). The heating principle options are gas-heated (lower energy costs) or electric-heated (clean & green & easy to use). Depending on the production needs and the available energy resources on-site, the appropriate equipment can be tailored and chosen.

| Type | Continuous | Intermittent |
| Features | Continuous material infeed and discharge; the conveyor belt or spiral system operates without interruption, offering a high degree of automation and large production capacity. | Batch-based processing; provides high flexibility, facilitating easy transitions between small-batch, multi-variety production runs. |
| Applicable Scenarios | Large-scale industrial production, 24-hour production lines | Small to medium-sized factories, pilot production workshops, and high-mix, low-volume production |
Intermittent-type models are available in several common configurations-single-frame, double-frame, triple-frame, and four-frame-and can also be customized to meet specific requirements.

Vegetable blancher is a kind of equipment in the vegetable processing production line. The working principle of the machine is that the machine includes a working box, a base, and four sets of legs. A working chamber is set in the working box, and the working box is provided with a take-in and put-out port, which is connected to the working chamber, and a cover is provided on the take-in and put-out port, and a heating plate is provided on the bottom wall of the working box; when using the blanching machine, just open the cover, inject water into the working chamber through the take-in and put-out port, and heat it through the heating plate, and then put the food to be blanched in it, and blanch it with high-temperature water. The machine can sterilize the food and maintain its color, texture, and flavor. The blanching time depends on the type of food and the required degree of cooking.
Advantages of commercial blanching equipment
1. Improved efficiency: Commercial blanching equipment is designed to process large quantities of food in a short period. This makes it ideal for use in commercial kitchens, food processing plants, and other industrial settings.
2. Preservation: The machine blanches food according to a certain water temperature, thus ensuring high quality and long-term storage of the product.
3. Hygiene: The commercial blanching equipment is easy to clean and is an excellent choice for use in environments with high hygiene requirements.
How does it work?
The material enters the blanching chamber via an inlet or conveying system, where it remains in hot water or steam at a preset temperature for a predetermined duration. Once this time has elapsed, the product is automatically discharged.
The following video demonstrates the workflow.

The blancher's job in a chicken-foot line is mainly to take off the yellow outer skin. From there, it's one continuous automated run: thaw, blanch, skin, wash, cut, then grade and pack.

FAQ
Q: What materials is the equipment made of?
A: All parts that come into contact with the product are made of food-grade SUS304 stainless steel. The frame, tank, conveyor belt, and covers are constructed entirely from stainless steel, ensuring corrosion resistance and ease of cleaning, in compliance with food hygiene standards.
Q: How precise is the temperature control?
A: The equipment is equipped with an automatic temperature control system. Temperature sensors provide real-time monitoring and automatically adjust the steam or electric heating input. The temperature control precision reaches ±1–2°C, ensuring consistent results for every batch of product.
Q: Is the water and power consumption high?
A: The water-bath type features a water circulation system, requiring minimal water replenishment; the steam-heated type consumes the least amount of water. For electrically heated models, power ratings range from 30 kW to 150 kW depending on the specifications. Steam-heated models offer lower operating energy costs. Actual energy consumption depends on production capacity, the type of material being processed, and local energy prices.
Q: Is the equipment easy to clean?
A: The tank features an open design with accessible covers and a removable conveyor belt. All welds are polished, leaving no sanitary "dead zones." The unit can be cleaned simply by rinsing with water, meeting food-grade sanitation requirements.
Q: How much does a stainless steel blancher cost?
A: Prices vary significantly based on the type, production capacity, and heating method, typically ranging from tens of thousands to over a hundred thousand RMB. Continuous-process machines are more expensive than batch-process ones, and there are also price differences between steam-heated and electrically heated models. We can provide a specific quote based on your required production output and process specifications.
Q: Do you provide on-site installation and commissioning?
A: Yes. We offer free on-site installation and commissioning services, along with on-site training for your operators, to ensure a smooth start to your production.
Q: What is the warranty period, and how is after-sales support handled?
A: The entire machine comes with a one-year warranty. We provide lifetime access to original factory spare parts and technical support, backed by both remote guidance and on-site service.
Q: Can you provide a complete production line?
A: Yes. In addition to standalone blanching machines, we can supply a full range of upstream and downstream equipment-such as washers, coolers, sorting conveyors, cutting machines, and dewatering machines-to provide a complete production line solution, from raw materials to finished products.
What are the precautions when using the machine?
1. Before using the machine, you need to check whether the various components and circuits of the machine are correct.
2. The machine needs to be disinfected and treated before use to ensure the safety of food.
3. When handling hot water or steam, use personal protective equipment such as gloves.
4. The machine needs to be cleaned and maintained regularly to ensure optimal performance.
