An apparatus and method for continuously producing constant weight portions of semi-solid matter, such as bread dough, from a large mass through a dividing mechanism whereby portions are formed on a receptacle which receives the portion so that an accurate weight indication of the portion can be taken. By separating portions of the mass with the divider, when the weight of the mass on the receptacle reaches a predetermined shutoff weight, constant weight portions are achieved. A drive motor may power the receptacle through a selectively disengageable motor drive connection, which can be disengaged to allow accurate weight indications. Variations in the weight of portions from a target portion weight may be minimized by automatically adjusting the shutoff weight at which the portion is separated by the dividing mechanism, according to the difference between the portion weight and the target weight.

What is claimed is: 1. A method of dividing semi-solid matter into portions comprising the steps of: providing a divider which opens and closes in response to control signals to separate the semi-solid matter into portions; providing a receptacle for receiving individual portions from the divider; mounting said receptacle to a load cell for producing electrical indications according to an applied load; providing a motor which operates in response to a control signal; connecting the motor to the receptacle with a disengageable connection which drives the receptacle when engaged, and provides a complete physical separation between the load cell and the motor when disengaged; sending a control signal to the motor to disengage the connection; sending an opening control signal to the divider to release semi-solid matter to the receptacle; determining the weight of the matter on the receptacle from load cell indications; sending a closing control signal to the divider to separate the semi-solid matter on the receptacle into a portion when the load cell indication reaches a predetermined shutoff weight; and sending a control signal to the motor to release the portion from the receptacle. 2. The method of claim 1 further comprising the steps of: inputting a predetermined target weight; determining the weight of the separated portion on the receptacle from load cell indications; determining the difference between the weight of the portion and the predetermined target weight; and adjusting the shutoff weight according to the difference. 3. The method of claim 2 further comprising the steps of: inputting a predetermined delay time; measuring the delay time following the sending of the closing control signal to the divider; and determining the portion weight from a weight indication received after the expiration of the delay time. 4. The method of claim 3 further comprising the steps of: defining predetermined weight limits for the portions; determining whether the portion weight falls within predetermined limits; and adjusting the shutoff weight according to the difference only if the portion weight falls within the predetermined limits. 5. The method of claim 1 further comprising the steps of: storing a value of the load cell weight indication in an empty condition; and determining the portion weight by subtracting the empty load cell indication from a weight indication received with the portion on the receptacle. 6. The method of claim 1 further comprising the steps of: inputting a value for a sample size N; determining an average portion weight of at least N portion weight indications; determining the difference between the average weight of the N portions and the predetermined target weight; and adjusting the shutoff weight according to the difference. 7. The method of claim 1 wherein said receptacle is rotatably mounted to the load cell. 8. The method of claim 1 wherein the receptacle comprises at least one roller. 9. A method of dividing semi-solid matter into portions comprising the steps of: providing a divider which opens and closes in response to control signals to separate the semi-solid matter into portions; providing a receptacle for receiving individual portions from the divider; mounting said receptacle to a load cell for producing electrical indications according to an applied load; providing a motor which operates in response to a control signal; connecting the motor to the receptacle with a disengageable connection for driving the receptacle; sending a control signal to the motor to disengage the connection; sending an opening control signal to the divider to release semi-solid matter to the receptacle; determining the weight of the matter on the receptacle from load cell indications; sending a closing control signal to the divider to separate the semi-solid matter on the receptacle into a portion when the load cell indication reaches a predetermined shutoff weight; sending a control signal to the motor to release the portion from the receptacle; weighing each portion in a group containing a predetermined number of portions; determining the difference between the average weight of the portion and the predetermined target weight; and adjusting the shutoff weight by the operating rate control signal by an amount equal to the average weight difference from the target weight multiplied by a predetermined moderating factor. 10. The method of claim 9 wherein the predetermined moderating factor is one. 11. The method of claim 9 wherein the predetermined moderating factor is a fractional number between zero and one. 12. The method of claim 9 wherein the group of a predetermined number of portions is limited to portions having a weight within a predetermined weight range. 13. The method of claim 12 where portions having a weight outside the predetermined weight range are identified. 14. The method of claim 9 wherein the predetermined weight range is approximately 75-125% of the predetermined target weight. 15. The method of claim 9 wherein the predetermined number of portions in the group is one. 16. The method of claim 9 wherein the predetermined time delay interval is between 0 and 1.0 seconds. 17. The method of claim 9 wherein the step of weighing each portion in a group containing a predetermined number of portions is performed by apparatus comprising a fluid restricted strain gauge load cell. 18. An apparatus for dividing portions of semi-solid matter comprising: a load cell for producing electrical indications according to an applied load; a receptacle rotatably mounted to said load cell for receiving individual portions; a motor which operates in response to a control signal for driving the receptacle; a disengageable connection between the motor and the receptacle which drives the receptacle when engaged and provides a complete physical separation between the load cell and the motor when disengaged; a divider which operates in response to a control signal located in proximity to the receptacle to separate the semi-solid matter into portions on the receptacle; a processor in electrical communication with the load cell, the divider and the motor, the processor programmed to receive electrical indications from the load cell for determining the weight of matter on the receptacle, and to send a control signal to the divider to separate the semi-solid matter on the receptacle into a portion when the load cell indication reaches a predetermined shutoff weight. 19. The apparatus of claim 18 wherein the processor is programmed to send a control signal to the motor to release the separated portion from the receptacle. 20. The apparatus of claim 18 further comprising an analog/digital converter. 21. The apparatus of claim 18 further comprising a dampening device mounted to the load cell. 22. An apparatus for dividing portions of semi-solid matter comprising: a load cell for producing electrical indications according to an applied load; a receptacle rotatably mounted to said load cell for receiving individual portions; the receptacle comprises at least one roller; a motor which operates in response to a control signal for driving the receptacle; a disengageable connection between the motor and the receptacle; a divider which operates in response to a control signal located in proximity to the receptacle to separate the semi-solid matter into portions on the receptacle; a processor in electrical communication with the load cell, the divider and the motor, the processor programmed to receive electrical indications from the load cell for determining the weight of matter on the receptacle, and to send a control signal to the divider to separate the semi-solid matter on the receptacle into a portion when the load cell indication reaches a predetermined shutoff weight.
