Equipment

In most grading / packing companies and egg breaking plants, the production begins with loading of eggs. In order to run an efficient plant it is therefore absolutely vital to have efficient and stable loading of eggs.

BTH AMERICA is specialized in supplying loading solutions for wet and dry conditions, and in optimum handling of different types and qualities of eggs, whatever they use paper or plastic trays or any combination could be used.

BTH AMERICA loaders are available for capacities up to 201,600 eggs/hour (560 cases/hour). All loaders are constructed by different symmetric modules, which can be put together in different layouts according to the layout requirements. To install BTH loaders, the space limitation in the process plant layout is no longer an issue.

Optiloader Plus Series

• The BTH AMERICA Optiloader Plus Series is a completely new generation of egg loaders. The target is to increase the capacity and the system optimization.
• Increased capacity.
• New stack infeed system ensuring the most accurate alignment in the de-stacker module, based on the dual-speed belt infeed.
• New retaining system for stuck eggs.
• New empty tray stack handling system, ensuring more stable and gentle stacking of empty trays.
• New vacuum system, improved suction, less energy consumption.
• Optimization of the drive system.

Egg loaders for egg graders

• These plus features are available on the 12 and 18 row optiloaders, and are also available in combi-versions (in-line / off-line) for the grading industry.
• With the combi-versions, it is possible to operate with a number of rows on the infeed table to be filled from the accumulator and the rest by the loader.
• The special swing arm construction ensures a synchronized speed between the eggs in the suction cups and the spools on the roller infeed conveyor.

The BTH AMERICA egg washers are the result of an intensive project, analyzing new ideas for egg washing in combination with the knowledge of years and long experience solving the challenges and problems our customers are faced with.

The BTH GENTLE WASH egg washer, built exclusively by BTH AMERICA, is the most gentle and effective egg washer on the market today. The unique brushing action plus a high volume, zero pressure wash solution delivery system.

The egg washers are capable of working with any kinds of eggs (nest-runs, grader eggs, dirts, leakers, “mud balls”, etc.) and are suitable to work in-line and off-line operations. No matter the conditions.

The Gentle Wash system

• Reduces egg losses.
• Reduces water and chemical consumption.
• Reduces / eliminates foam problems and the need for defoamer.

Why washing matters before breaking

Due to the high cost of eggs, when the egg has been broken on the breaking machine it is vital that every single egg is drained completely. This may seem an easy job, but with the different sizes and qualities of eggs it requires highly specialised equipment. A second requirement for today’s manufacturer is the separation of yolk and albumen — the demand for specialised egg products is increasing, and the foundation for this is clean albumen and high solids yolk.

A variety of alternative schemes; the final solution can be used for any type of pasteurizer.

BTH AMERICA ESL pasteurization was the first real innovation system and can extend the shelf life of product protection attributes. By combining BTH dedication to innovation and commitment to the egg processing industry with the latest liquid processing and heat transfer technology from USA and Europe, BTH has developed an entire range of egg product pasteurization systems.

General — ESL

ESL after pasteurization, meant to extend the shelf life (ESL) of liquid egg products, is almost three times as long as compared with the life of a conventional liquid egg product. Shelf life extension of the adjustment is in the process of pasteurization, exposing the eggs for the time needed for heating.

What the system delivers

• Highest possible bacterial reduction = shelf life.
• Best product performance.
• Highest energy efficiency.
• Lowest operating costs.

Precise control

Power control is accurately metered and may be recorded. A meter constantly displays the amount of power being applied to heat the product.

Quick response

The full range of power control from minimum to maximum is traversed in seconds. Adjustments take effect immediately. Thermal lag time is zero. Automatic changes in power level due to physical properties or size of load are instantaneous.

Liquid product handling

After breaking the egg into whole egg, or separating the yolk from the albumen, the egg must be filtered, cooled and if necessary mixed with salt or sugar to match the need of the end-user. In order to maintain a superior quality and secure a long shelf life, it is vital to keep this process as clean and cool as possible. With the patented automatic filter systems in combination with a specialized knowhow on plant design, BTH AMERICA is able to supply installations which will meet the hygiene requirements of today as well as tomorrow.

Heat exchangers and control

BTH AMERICA pasteurizers are specially designed for the egg processing industry and are available with either plate and/or tubular heat exchangers. Gentle handling and accurate temperature control are two of the key elements that have been optimized in the pasteurizer to ensure highly efficient pasteurization and achieve a high-quality output.

Product properties

The challenge of pasteurizing is first of all to achieve as long a shelf life as possible while at the same time maintaining the unique product properties of the egg and supplying the specialized products which will match the needs of your customers. The product properties must be secured irrespective of whether standard whole egg or specialized salted or sugared products are pasteurized. From the wide selection of different modules we customize the pasteurizer to match your specific requirements with regard to the raw material fed to the pasteurizer and the requirements of your customer.

Capacity and compliance

The pasteurizers are available with capacities from 600 to 10,000 l/h in standard configurations. Lower and higher capacities are available on demand. All BTH AMERICA pasteurizers are built in accordance with the EC rules, or USDA or CFIA, depending on the country of destination.
