An apparatus or method for weighing and/or measuring the flow rate of quantity of a particulate flowing out of a hopper wherein the hopper is isolated from the other components of the apparatus. The apparatus and method are adapted to generate a decoupling point boundary that demarcates the total amount of particulate in the hopper into portions that are not fully supported and portions that are fully supported by the hopper. The particulate is in continuous contact with itself from the inlet to the outlet, with the particulate contained between the isolated hopper and the rest of the components of the system by a flexible coupling or some other method of containment. The invention has the advantages of higher accuracy, decreased cost and complexity, and greater reliability than other solid particulate weighing systems of the prior art, particularly when dealing with low density particulates.

A method of controlling an upstream and a downstream process wherein the upstream process conditions a stream of product delivered to the downstream process is provided. The control method uses an empirically determined formula to determine a metric for adjusting the activity of the upstream process to thereby adjust the rate with which the upstream process conditions and feeds a stream of conditioned product to the downstream process. The empirically determined formula determines the metric using two input variables: a duty cycle setting of the upstream process and an output rate of the downstream process expressed as a decimal amount of the output rate set-point.

Provided is a device for weighing a wide variety of ingredients and a system configuration of the device for weighing a wide variety of ingredients, the device weighing and feeding several types of ingredients when cup noodles such as instant noodles are packed with the ingredients in a cup. A space-saving and easily maintainable device for weighing a wide variety of ingredients, wherein powdery and granular starting materials (A, B) are individually stored in a first starting material hopper (2) and a second starting material hopper (3), gradually sent out to the downstream side, weighed, discharged to a first chute (10) and a second chute (11), and supplied to a cup-filling unit (23), and one series from the first starting material hopper (2) to the first chute (10) and one series from the second starting material hopper (3) to the second chute (11) are formed vertically parallel in the shape of a staircase from the upstream side to the downstream side. The device can mix a wide variety of ingredients, improves workability by the size and weight reduction of the starting material hoppers, and achieves space saving resulting from the reduction of floor space to half, and easier cleaning.

A discharge flow rate of a loss-in-weight scale is controlled by continuously changing control outputs to save the time necessary for data stabilization. A curve relating the discharge flow rate and the control output is obtained by using the functional relationship between the control output and time and the functional relationship between the material weight and time. The discharge flow rate can be precisely controlled by directly selecting or inputting a value of the control output, to achieve the objectives of direct controlling and of avoiding the time for data stabilization.
