Improved apparatus and method for forming lightweight edible products
摘要:
A doughnut making machine and apparatus has a hopper (18) for the dough of a type which exudes gluten or other sticky substances when compressed, the hopper (18) terminates in a lower cylinder (20) which co-acts with the cutting surfaces on a lower cutting piston (26). An extruding piston (24) pushes the dough out between the cutting edge (22) of the cylinder and the cutting piston (26) and, thereafter, with retraction of the cutting piston (26), the dough is severed into a conventional toroidal shape and falls in cooking oil in a frying tank. Cooking oil from the frying tank is distributed onto the cutting edges of the piston and the cutting edge of the cylinder by various distribution techniques. Cooking oil is picked up from the frying tank using a dipstick (30) and is transmitted to the dough cutting surfaces using gravity and capillary action. The method by which doughnuts are extruded in a generally toroidal shape while distributing a film of cooking oil onto the dough cutting surfaces and then severing the formed toroidal shaped doughnut from the cutting surfaces whereby the doughnut contacts the cooking oil on the dough cutting surface and freely releases from the cylinder's cutting edge.
