What is a food screw conveyor?

Food screw conveyor, also called food grade screw conveyor, is a screw conveyor specially designed for the food industry, which can convey or load powdery and granular food products such as flour, sugar, milk powder, seasoning, additives, salt, etc. To the filling machine, it is made of food-grade stainless steel (SUS304 or 316L stainless steel), highly polished stainless steel structure, no pits or gaps, which is our industry standard, no leakage, no contamination of food, tube length and The angle of inclination can be customized according to customer requirements, and they can be customized to handle different types of food products, with features such as variable speed control, adjustable discharge height, and various inlet and outlet configurations.

What is the Food Screw Conveyor for?

Food Screw Conveyor can be used to handle a variety of food materials in different states, dry, loose, or wet. In actual production, Food Screw Conveyor is usually combined with bulk bag unloader, Big Bag, mixer, crushing machines and other equipment. The following is the introduction of several applications of Food Screw Conveyor:

1. Food powder processing

Many food powders have different consistencies depending on the food powder. Some are dry, some are wet, and some are greasy. The Food Screw Conveyor is able to handle a wide variety of different types of products without requiring extensive system maintenance. Plus, the Food Screw Conveyor consistently delivers product, helping food processors keep up with production demand.

2. Food raw materials

For those processing ingredients such as sugar, flour, spices and grains, sanitation and efficiency are an absolute must, but many also need the flexibility to handle loading large quantities of material into conveyor systems. Therefore, many people often use the multifunctional design of the Food Screw Conveyor when handling bulk materials, such as adding moving wheels at the bottom.

3. Brewing

In the process of brewing beer from grain, breweries need to transfer large quantities of hops from storage plants to large brewing tanks, where it is filled with water and the fermentation process begins. The Food Screw Conveyor does an excellent job of efficiently metering hops and grains during the brewing process, the included Food Screw Conveyor is able to move the material without degrading the product, thus preserving the rich flavor and aroma present in the product.

4. Dairy products

Dairies often turn excess milk into powdered milk -- which has a longer shelf life than liquid milk. To achieve this goal, milk powder processors need a hygienic system that can efficiently transport their products. Large-scale manufacturers can simply opt for sealed ducts for moving powder throughout the facility and degrading the product, but their length and space-demanding nature make them unsuitable for processors with smaller facilities.

For smaller facilities, the sloped Food Screw Conveyor is a great option, allowing plants to make the most of the space without giving up any basic hygiene requirements.

Details of Food Screw Conveyor

The details of Food Screw Conveyor are shown below:

1. Overall: stainless steel body, polished and polished, clean and smooth

2. Self-contained hopper: cooperate with feeding equipment to receive food, with certain buffer and storage functions

3. Fully sealed pipeline: avoid food leakage

4. Upper drive motor: the material can be subjected to greater tension and the lifting capacity is stronger

5. The feed end is designed with a movable outlet: it is convenient to clean the inner wall of the machine

Food Screw Conveyor Selection Considerations

When selecting a food screw conveyor, several factors need to be considered to ensure it meets the specific requirements of your application. Here are some key considerations:

1.Material Compatibility: Ensure that the materials used in the screw conveyor are food-grade and compatible with the specific type of food being transported to prevent contamination.

2.Sanitary Design: Choose a screw conveyor with a sanitary design that is easy to clean and maintain to meet food safety standards.

3.Capacity and Throughput: Consider the required capacity and throughput of the conveyor to ensure it can handle the volume of food material required for your process.

4.Screw Configuration: Select the appropriate screw configuration (e.g., shafted or shaftless, single or multiple screws) based on the characteristics of the food product and the layout of your processing facility.

5.Operating Environment: Consider the operating environment, including factors such as temperature, humidity, and exposure to moisture, to select a conveyor that can withstand these conditions.

6.Safety Features: Ensure the conveyor has safety features such as guards, emergency stops, and overload protection to prevent accidents and protect personnel.

Food Industry Solutions

Food screw conveyors are versatile pieces of equipment that can be used in a variety of applications in the food industry. Here are some examples of how screw conveyors can be used with other equipment to create complete conveying and packaging solutions:

1.Food screw conveyor with a vibratory screener: This combination is often used to remove impurities and debris from bulk food products before they are conveyed to a packaging machine.

The vibratory screener separates the larger particles from the finer particles,

2. Food screw conveyor with a packaging machine: This combination is used to automatically package bulk food products.

The screw conveyor delivers the product to the packaging machine, which then measures and packages the product into bags, cartons, or other containers.

3. Food screw conveyor with mixer: This combination is used to mix bulk food materials. The screw conveyor conveys the materials to the mixer, and then the mixer mixes the materials evenly.

In addition to the above common matching solutions, food screw conveyors can also be used in conjunction with other equipment, such as filling machines, storage tanks, etc.
