Snack food conveyors come in various types to satisfy different operational demands. These systems guarantee that delicate products are transferred without harm, where speed and efficiency are essential, and even in challenging environments.
Belt conveyors
The most often used conveyor for transporting several types of snack foods is the belt conveyor. A strong, long-lasting belt typically made of PVC or rubber covers this equipment's moving components. Because of its versatility, a belt conveyor is helpful for transporting bags, boxes, and bulk materials. Belt conveyors may be adjusted to move items at several angles and in various sections of an industrial building. It is also suitable for transferring heavier products in larger products, such as extruded ones, chips, or packaged goods.
Auger conveyors
An auger conveyor is a spiral screw-shaped conveyor used to transfer bulk dry materials such as cereals, nuts, seeds, and powdered products, unlike a belt conveyor. These conveyors are famous in the packing area when precision and control of the product flow, such as measuring and filling, are required. Auger conveyors take up much less room since they transport materials in a compact, space-saving manner.
Vibrating conveyors
Snack foods such as nuts, granola, or dried fruits that must be moved gently without squashing the goods frequently employ vibrating conveyors. A perforated or solid trough or tray makes up this equipment, which vibrates to move the product. Due to their propensity toward screening and separating, vibrating conveyors are frequently seen in the primary product transfer process. They are effective because they cause minimal disturbance to the material being moved.
Wire mesh belt conveyors
Wire mesh belt conveyors are suitable for transporting hot or fragile snack items, including fried or baked goods, since they provide greater airflow. Steel, stainless steel, or bronze wire form this robust, permeable belt. Food products with an open structure, such as pretzels, popped corn, and fried snacks, do well on wire mesh belts because they permit heat and moisture to escape. They are also beneficial for heavier items or those conveying systems more vulnerable to damage. Due to their strength, they perform marvelously in extreme conditions.
Bucket elevators
Bucket elevators are useful in transporting snack foods vertically. Buckets built of plastic, metal, or a combination hold the materials on a belt or chain. They are excellent for shifting bulk products, such as powders or pellets, from one production process to another. These elevators ensure good space utilization and avoid product spillage during the transfer.
Snack Food Conveyors have a lot of uses in various sectors. Integrated transportation systems boost productivity, assure quality control, and satisfy client requests in these settings. Several examples are shown below.
Manufacturing industry
In the snack food production process, conveyors are crucial. They streamline the transportation of raw materials, such as grains and seasonings, from one processing stage to storage and load out. Belt conveyors are especially valuable for carrying heavy materials like flour or oils required in manufacturing. Vibrating and auger conveyors also assist delicately transporting lighter items such as nuts, seeds, and powders. Snack food conveyors effectively move large quantities of products, whether raw or processed, from manufacturing to packaging.
Warehouse and distribution centres
Snack food conveyors are vital for order fulfillment efficiency in warehouses and distribution centres. When transporting packaged goods, palletized items, or boxes to various warehouse locations, belt conveyors assist in sorting systems. Conveyors aid in the organization and preparation of products for dispatch by transporting items to packing stations. Fast food conveyors are also employed to ensure the timely movement of items, lowering manual handling and increasing warehouse space.
Food processing facilities
Snack food conveyors are critical to ensuring food safety and production effectiveness in processing facilities. They transport items such as fruits and vegetables, meat, grains, and dough through washing, cooking, coating, baking, frying, and cooling. Vibrating and wire mesh conveyors efficiently transport fragile or delicate items without damaging them. Furthermore, these conveyors are frequently made of food-safe materials that are easy to wash to meet FDA safety standards.
Retail and catering systems
Snack food conveyors control the flow of items in retail and catering businesses, such as food markets, vending machines, and concession stands. Belt conveyors can carry packaged snacks through food retail outlets and vending machines. Concession stands and buffets use auger conveyor systems to serve hot snacks like popcorn, nachos, or candies. These systems maintain constant product availability while improving the customer experience.
Industrial and Commercial Sectors
Apart from the food processing industry, snack food have multiple uses in industrial settings where bulk materials are handled. These conveyors can transport items like granola, cereal, seeds, or dried fruits. In these environments, auger and belt conveyors are commonly used due to their efficiency in moving bulk materials. These systems are also crucial in preventing product caking or clumping during transportation and storage.
Snack food conveyors have various designs and materials, with each component serving an essential purpose for the system's effectiveness, longevity, and ease of maintenance. These variables are vital to consider when building a conveyor system that meets operational needs and adheres to strict hygiene requirements in the food industry.
Design considerations
The conveyor system's design depends on the items transported, the distance covered, and the environmental factors involved. Key design elements include:
Conveyor type: Belt, auger, vibrating, wire mesh, or bucket elevators handle particular goods and applications. Belt conveyors handle heavier items, while auger conveyors work well with bulk dry materials.
Length and Inclination: Horizontal or inclined, the length of the conveyor must be appropriate for the space and the vertical/ horizontal distance required. Inclined belt/conveyors are required for steep inclines. Shorter versions cannot surpass 30-degree inclination.
Load capacity: The conveyor system must withstand the heaviest expected load. Larger motor drives or heavier-duty designs are necessary for bigger loads.
Speed and precision: Certain conveyor types, like augers, require high accuracy in feeding or metering. Moreover, a proper choice of speed is critical as faster speeds may result in product damage.
Material considerations
Choosing materials for construction is vital for the durability, hygiene, and functionality of the conveyor system, hence for snack food conveyors.
The predominant materials used to manufacture the conveyor frames comprise: stainless steel, aluminum, and carbon steel. Stainless steel is ideal for hostile conditions where moisture is a factor, while carbon steel is appropriate where cost is highly valued and not in very moist environments. Aluminum is lightweight with excellent anti-corrosion properties that suit light-duty applications.
Maintenance and hygiene considerations
Easy cleaning and maintenance are indispensable for food conveyors due to hygiene requirements in the food business. Frequent washing or disassembly must be avoided. Conveyors with open designs are easily hosed, while those with closed hoppers and tubes are harder to clean. Wire mesh belts are noted for being easy to clean because they are open textured. The materials used in construction must endure chemicals used in cleaning. Maintenance is crucial to sustaining the lifespan of a conveyor. Therefore, lubricant points must be readily serviceable, and wear-resistant parts fitted where they can easily be replaced.
There are so many factors to consider when choosing the correct conveyor system that it is no small task. Suitable equipment means meeting the client's needs and operational requirements and ensuring health and safety regulations are complied with. The following factors should be considered when choosing a conveyor for snacks.
Product characteristics
The product characteristics to consider are the conveyor's weight, form, dimensions, and temperature. For example, the belt type needs careful consideration, as thicker belts are needed for heavier products. Fragile equipment like wire mesh or vibrating systems needs special handling solutions. Snack conveyors need special attention paid to wider belts for bigger items such as potato or corn products and tighter belts for smaller food such as pretzels and nuts. High heat and low moisture products require special materials and additional cooling system equipment.
Application requirements
Knowing the client’s application requirements is crucial for making the right equipment choices. Key factors are performance requirements for speed and incline degree formations in the conveyor design. For example, food processing waits require extreme accuracy, while distribution centers are okay with average food conveyor speed. Certain liquids like soups require extreme caution when transporting them. Bulk foods like cereals call for auger conveyors and belt conveyors for packaged products. Vertical and horizontal configurations move anything left to right and up and down. Therefore, integrating more complicated systems is necessary.
Food safety and hygiene standards
The food industry composes safety standards, including USDA and FDA compliance. This is where the sanitation level and the hygiene cost come in. There are sanitary conveyors available that meet cleanability standards and anti-contamination level safety measures. USDA-fabricated equipment like post-wash conveyor systems meets the hygiene standard without much expense. Material choices must fulfill business food safety standards.
System cost
Cost is always an important consideration. Total costs include installation, operation, and maintenance and not just the upfront costs. Operating expenses comprise energy bills, labor, material, and maintenance costs. Maintenance costs are about the frequency and difficulty of anticipated repairs. System efficiency measures factor in time saved or standard work enhanced. Cost-effective systems lower expenses with fewer breakdowns and easy maintenance.
