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.

What are the advantages of Food Screw Conveyor?

Gentle on Foods

The spiral blade design helps minimize product spoilage and breakage.

Versatile Uses

Food-grade screw conveyors can be used to transport a wide variety of food products, including dry bulk solids, powders, and granules.

Hygienic Design

Food screw conveyors are typically made of stainless steel, making them easy to clean and sanitize. They are also designed to minimize areas where food can become trapped and harbor bacteria.

Closed System

The closed design of the screw conveyor helps protect food from dust, dirt, and other airborne contaminants.

Durable

Food-grade screw conveyors are built to withstand the rigors of food processing environments.

Safety Features

Such as guards, emergency stop buttons, and overload protection ensure safe operation in food processing environments.

Material Description of Food Screw Conveyor

The material of Food Screw Conveyor can be divided into 304 stainless steel and 316L stainless steel. The material differences are as follows:

304 stainless steel can withstand high temperature of 800 ℃, and has the characteristics of corrosion resistance, easy processing and good toughness. When the requirements for corrosion resistance are not high, 304 stainless steel is better, because the unit price of 304 stainless steel is lower than that of 316L stainless steel.

316L stainless steel is a material with lower carbon content in the same series. Compared with 304, 316L stainless steel has stronger chemical corrosion resistance, and is more resistant to high temperature creep, stress rupture and tensile strength than other steel types. When the application scene When there are higher requirements for corrosion and heat resistance, 316L stainless steel is better.

304 and 316 stainless steel comparison
Serial number comparison item	Comparison item	304	316L	Remark
1	price	Low	high	304 stainless steel has excellent performance, low unit price, and is more widely used
2	Molybdenum content%	0	2-3	The higher the Mo content, the better the corrosion resistance and heat resistance
3	Nickel content%	8-10.5	10-24	The higher the Ni content, the better the corrosion resistance and heat resistance
4	Carbon content%	<0.08	0.03	The higher the C content, the stronger the hardness; the lower the C content, the better the welding performance
Note	1: When we refer to 316 stainless steel, it refers to 316L stainless steel 2: Carbon is a strong austenite forming element, which can significantly increase the strength of steel, but the higher the carbon content in carbon steel, the worse the plasticity, and carbon also has an adverse effect on corrosion resistance

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

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.
