The invention provides a production method for bean paste, wherein the method includes the following steps: A, selecting dry
chili pepper meeting standards, then successively cleaning with a cleaningmachine, steam-cooking with a steam
cooker, injecting
saline water and carrying out crushing treatment with a
crusher, sending into a stirrer after crushing, then inputting into a main
fermentation tank by a
chili pepper blank transport pump while stirring, and fermenting, to obtain a
chili pepper blank; B, inputting broad bean halves into a rinsing
steaming cooling device, rinsing and
steaming, cooling, and transporting to a disc koji-making device and koji-making while inoculating with a bacterial
powder by a transporting inoculating device; and after koji-making, inputting into a broad beanhalves
fermentation tank, and fermenting to obtain broad bean paste halves; and C, inputting the chili pepper blank obtained in the step A and the broad bean paste halves obtained in the step B intoa
mixing tank, mixing evenly, inputting into the main
fermentation tank by a feeding pump, and fermenting to obtain the Pixian bean paste. The method is mechanically operated in the whole process, theprocess control is more convenient and accurate, the
flavor and quality of the Pixian bean paste are guaranteed, and at the same time, the truly feasible equipment base is provided for large-scale production and industry upgrading of the Pixian bean paste.
