AUTO FEEDING, AUTO DOSING TO CONTINUOUS MIXER FOR EFFICIENTLY MAKING HIGH QUALITY DOUGH FOR BAKERY INDUSTRY

摘要

This invention is based upon auto feeding, auto dosing to continuous mixer for efficiently making high quality dough for bakery industry. The mechanism is as follows. Pre-weighed material like sugar, milk powder, chemicals, preservatives and liquids like lecithin, malt glucose, water and inverted sugar syrup which go in to the making of the dough are fed in to a creaming machine called Creamer in which the cream is made up by agitation. This cream is then fed in to a tank which is mounted on load cells to ascertain the exact weight of the cream to be pumped out. The cream in this tank is circulated through pipe lines and when the cream is to be fed in to the continuous mixer, the valve fixed above the continuous mixer is opened and the cream is fed in to the continues mixer in the exact quantity as required. Before the cream is fed in to the continuous mixer, the cream mass is determined by a mass flow meter fixed on the pipe line. Another ingredient is flour which comes from the flour handling system and is fed to the flour cyclone. From the flour cyclone, small quantities of flour are fed in to an augur feeder. From the augur feeder, the flour is fed through a screw system in to a conical hopper fixed with load cells (weighing pans) to determine the weight of the flour to be fed in to the continuous mixer. In the continuous mixer, pre-blending of the cream and the flour takes place in the pre-blending section of the machine. The dough thus made is then kneaded for consistency, elasticity thereof in the kneading section inside the cylinder. The whole process of pre-blending and kneading the dough is achieved by mechanism of horizontal screws inside the cylinder of the continuous mixer, hi this invention each stage of the operation from the feeding of materials into the creamer and feeding of flour and then the mixing of these in the continuous mixer is controlled by PLC (Programmable logical control).Data for these various operations are fed into the PLC. Therefore accurate feeding and proper mixing are achieved. It has a versatile design applicable for multiple products like-Bakery, biscuit, chocolates, confectionery, dairy and dessert thereof.
