A kiln including a stove and a heat source wherein the stove includes a chamber, an air guide structure, an exhaust pipe and a heat storage member. The chamber includes a cavity, an entry, and an air outlet. The air outlet is located between a top of the front section of the cavity and the entry. The air guide structure communicates with the air outlet and includes a guide plate. The exhaust pipe is disposed above the guide plate, and an exhaust channel is formed by the guide plate of the air guide structure and the exhaust pipe. The heat storage member covers an exterior of the cavity which is corresponding to the top of the front section of the cavity, and contacts the air guide structure. The heat source is disposed in the stove and adapted to heat the cavity.

A pastry making machine comprises a conveyor with product molds on the matrices. Stamps are adapted to cover matrices. A dough dispenser with a hopper is installed at the beginning of the conveyor. There are also an oven, a product unloader, a blower with rolls, a manipulator equipped with a lifting mechanism and magnetic or mechanical grippers for the stamps, and a control unit. The surface of the rolls is profiled with separating cells forming longitudinal and transversal rows. The dosing head has at least one row of separating chambers, with channels discharging dosed dough pieces. An induction heating assembly is positioned along the oven. Each matrix is mounted on a wheeled cart, attached to the conveyor. One embodiment has a current-conductive profile connected to the heating assemblies of the stamps. Another embodiment has its heating assembly stretched alongside the whole oven heating the stamps and matrices. The machine improves product quality.

Techniques for utilizing excess heat generated by an oven to generate electricity are provided. In one example, an oven can comprise a coolant pathway positioned adjacent to a hollow space within the oven, wherein the hollow space can contain heat. The oven can also comprise a chamber in fluid communication with the coolant pathway. The oven can further comprise a turbine in fluid communication with the chamber and an outlet. Moreover, the oven can comprise a generator connected to the turbine, wherein rotation of the turbine can power the generator.

The present disclosure includes a system for power management of a plurality of heating sources for an electric range. The system includes a cooktop element, an oven element, and a switch in electrical connection with the cooktop element. The switch is configured to supply a first voltage or a second voltage to the cooktop element from a voltage source. The system further includes a controller in communication with the oven element and configured to control the at least one switch. The controller is configured to control the switch in a first state and a second state. In the first state, the controller controls the switch to supply the first voltage to the cooktop element in response to an off-state of the oven element. In the second state, the controller controls the switch to supply the second voltage to the cooktop element in response to an on-state of the oven element.

An oven appliance includes a baking stone positioned within a housing at a bottom portion of a cooking chamber. An inlet of an air duct is positioned at a front portion of the housing, and an outlet of the air duct is positioned at a rear portion of the housing and is contiguous with ambient air about the housing. An air handler is configured for urging the ambient air about the housing through the air duct.
