FoodSafety IRD

In numerous food products, such as spices, herbs, seeds, nuts, teas, vegetables, and fruits, the continuous FoodSafety-IRD can be utilized for sterilization, pasteurization, roasting, coating, drying, and destroying insects and larvae.
 
The FS-IRD allows a high degree of flexibility if you need to adjust your production process, process new or different products, or encounter new requirements for your product. The FS-IRD can be physically reoriented with very little effort.

How does it work?

The infrared module and the horizontal rotary drum, in which a spiral screw is shrink-wrapped, are essential components of the FS-IRD.
A volumetric metering unit continuously transfers material. The material is then evenly conveyed through the machine and treated with infrared light as it flows through the spiral at a variable turning speed. Water can be added to the food during treatment if necessary.
The material falls into the output hopper at the end of the rotating drum and can be transferred directly to the next production process.

The FS-IRD is available for a wide range of throughputs. Depending on the task, the bulk weight, and the flow characteristics of the foods to be treated, the machine will be custom-designed. Different peripherals can be added to the machines, and easily combined into entire systems.

Food Safety solution

In recent years, food safety has become more significant. No one can afford to send unsafe food onto the market, whether they are manufacturers, processors, or traders. Errors in the material flow chain can cause product recalls if they exceed acceptable limits and harmful agents are discovered.
 
This has major financial implications for suppliers. The reputational harm caused by a recall, on the other hand, is far worse. As a result, food safety is under question. More and more manufacturers are opting for the continuous FS-IRD to deal this uncertainty.

Continuously Unlike many other procedures, the FS-IRD operates continuously. The product volume is available for continuous processing.The continuous process prevents any mixing of already sterilized with unsterilized products
Minimal energy consumption The direct introduction of infrared energy to the product results in a lower energy consumption. The energy is immediately channeled into the product's core. It is not necessary to have an energy-laden hot flow of air, like in convective thermal processes. Due to the sheer movement in the rotary drum, the treatment process in the FS-IRD takes only minutes and is especially gentle. Because no pre-heating of the device is required, the energy balance achieved is very positive. There is no energy loss due to intermediate heat-transfer mediums. As a result, the device is extremely efficient.
Immediately. The production run can begin immediately upon startup. The machine does not need to be warm up phase.
Products Whether you want to pasteurize, sterilize, or dry your product, which may be Cereals - dried fruits - flowers - herbs - grains, nuts - seeds - spices - teas - vegetables, or something else, there is a solution for you.

Constantly in motion The rotation of the drum ensures that the material is constantly moving. The spiral coils and mixing elements custom-made for your product ensure an optimal material mix while preventing clumping. Your product is treated evenly. There is no material dispersion due to the drum's low rotation speed. 
Spraying To protect product sensors, a measured spray of water can be used to cool the particles from the outside.
Short dwell-time The product is only in the FS-IRD for a few minutes before being available for further production steps.
Dosing A consistent quantity of material is provided for the process with dosages adapted to your product.
Capacity expansion. Due to the small FS-IRD's footprint and ease of integration, capacity expansion is easy. In comparison to conventional machines, the machine's compact design significantly reduces your footprint.
Low maintentance costs Low wear and tear on parts ensures low maintenance and spare-parts costs.
Operating system The integrated controlling system stores recipes and process parameters. This allows you to change products or change product properties while ensuring reproducible results.

Tekemas Sterilization icon

Sterilization & Pasteurization

Food in bulk, such as nuts, seeds, spices, tea, herbs, leaves, dried vegetables, grain, cereals, dried mushrooms, as well as sliced, chopped, and powdered food, can be treated with infrared light to significantly reduce the microbiological load. Insects, larvae, and eggs are destroyed during the sterilization and pasteurization processes. The products are continuously mixed together. Each particle receives the same treatment in terms of duration and temperature. There are no dead zones. The process protects the organoleptic properties, which means that color, taste, volatile oils, odor, and valuable substances and vitamins are all protected. At the same time, pathogens such as salmonella will be destroyed. TPC, yeast, mold, E. coli, and coliforms can all be reduced safely. It is a completely natural process with no use of gases, chemicals, or additives.

Tekemas - Food Coating icon

Food Coating

What you can expect is the following: Liquid & dry seasonings applied with one coating system.Sprayable, water-soluble additives such as salt, flavors, color, Other sprayable additives. Products are continuously mixed. Uniform coverage of the product. No dead spots. Every particle receives the same treatment. Maximized seasoning-coverage & minimized waste in the process area.

Tekemas- food roasting icon

Food Roasting

The product to be roasted is heated from the inside as well as from the outside using the infrared light working principle. The roasting process is thereby made gentler. As a result, heat diffusion is slow and uniform, and flavor and aroma development can be slow. The method of only burning from the outside – as with conventional convective treatment methods – is omitted. In contrast to traditional convective treatments, this new procedure is controlled by very fast and precise control of product temperature rather than the temperature of the heat transfer medium. Infrared light that has been focused penetrates beneath the surface of the product particles and is converted into heat in the interior. The desired degree of roasting is achieved in a very short time and with maximum product protection.

Tekemas - Food Drying icon

Food Drying

The reverse-working principle of infrared light improves the final product's quality. Flavors can be released during the drying process in some products. This reverse-working principle of infrared light, in which energy penetrates to the core of the product, also provides an efficient use of energy and clear advantages over other methods. The continuous rotation of the FS-IRD and the resulting mixing of the product ensures a very homogeneous drying process. As a result, the formation of nests is avoided. When the FS-IRD is used in a combined drying for a quick and gentle end-drying, the products are automatically germ-reduced and stock-protected. The FS-IRD can be used as a booster before a conventional dryer. Within minutes, the material can be heated to a high temperature. As a result, the product's heat can be used in the process.

Tekemas - stock protection icon

Food Stock

These two critical steps in the processing of cereals, nuts, seeds, and dried fruits are critical for ensuring sterility, shelf-life, and quality: Disinsectization to ensure sterility and shelf-life of food, as well as processing for a high-quality, healthy, and one-of-a-kind product. The FS-IRD allows you to combine two steps into one: Insects, larvae, and eggs are destroyed during the pasteurization process without causing protein damage. It not only kills insects and eggs in a safe manner without the use of gases or chemicals, but it also provides you with a high-quality product and protects your supply stock.

FoodSafety Rotary Cooler

After thermal treatment and before packaging or warehousing, every natural product requires a cooling step. The FoodSafety-Rotary Cooler was created for food applications that have stringent food safety and hygiene requirements. Spices, herbs, seeds, teas, vegetables, fruits, nuts, coffee, and cereals can all be cooled using the FS-RC.

The material is gently mixed in the drum before being conveyed from the inlet to the outlet. Even delicate items like nuts, seeds, and grains can be treated. This continuous working process ensures material first-in/first-out and exchanges the product's surface many times. Depending on the process and product, the product is cooled by ambient or chilled air while being mixed and conveyed. An exhaust ventilation system removes the hot and humid air. Furthermore, the drum can be cooled to accommodate high-temperature products such as roasted nuts.

Another significant advantage is the ease with which the FS-RC's can be cleaned, which significantly reduces cleaning downtime. Another option is a coating module inside the FS-RC, which allows the product to be coated with flavors, oil, salt, sugar, and other ingredients.
