Tunnel bakery ovens A2-KHPK are designed for baking of wide range of bread and bakery products (including from a mixture of rye and wheat flour).

The design of the oven has a high degree of prefabrication and arrives at the place of installation in the form of transportable units or large assembly components that provide the minimum time for its assembly and reliability of systems operation. The steam humidification section is located in the beginning of the oven and is designed for hydrothermal processing of the dough pieces by means of saturated steam delivered centralized or, that is preferred, generated in the steam generator built in the oven. Special tubular comb with nozzles is used for supply in the steam chamber.

At the customer’s request, an additional unit for hygrothermal processing of dough pieces can be installed in the area of steam humidification that improves the quality of baked products, especially products made from wheat flour.

In order to reduce the consumption of steam for hydrothermal processing of the dough pieces and thermal power in the oven A2-KHPK the steam generator integrated in the construction of the oven is provided. Produced in it steam by its properties meets the requirements of the technological parameters of hydrothermal processing of the dough pieces that allows reducing its consumption for steam humidification. So, when baking long loaves from high-grade flour, it is consumed usually up to 220 kg of steam per ton of product for hydrothermal treatment in tunnel bakery ovens and up to 400 kg of steam in furnaces with a dead-end baking chamber and up to 120 kg of steam per ton of product in ovens A2-KHPK.

Bakery ovens operating on liquid and gaseous fuels have pipes for discharging the products of combustion. The temperature of the fuel combustion products that are discharged may exceed 300 degrees Celsius. There are various designs of heat recovery units. In some cases, the heat recovery unit serves to heat the air, which can be used for drying magazines in the proofer or for heating industrial premises. In other cases, the heat recovery unit is used to heat water, which can be used for technological purposes.
