After a silicon material is put into the single crystal furnace, the method comprises the following steps for controlling: (A), heating to a low temperature according to the power of 40 to 45 kilowatts per hour, and keeping a constant power for 15 to 30 minutes; (B), heating to a medium temperature according to the power of 65 to 75 kilowatts per hour, and keeping a constant power for 15 to 30 minutes; (C), heating to a high temperature according to the power of 75 to 85 kilowatts per hour, and keeping a constant power; D, when 3 to 5 percent of silicon material is not melted in the furnace, cooling to a medium temperature according to the power of 65 to 75 kilowatts per hour, and keeping a constant power for 30 to 60 minutes, so that the silicon material is completely melted; and E, seeding. By adopting the method, the power value is gradually improved for gradual heating of the single crystal furnace, the silicon material can be promoted to fully absorb heat, and a small part of silicon material is melted by using waste heat, so that energy consumption is reduced; and experimental results show that the service life of a graphite heat field is remarkably prolonged and can be prolonged from average 40 times of use to 70 times of use in the furnace.

The present invention provides a process of corn starch sugar producing by an enzymatic technique. The process step mainly includes hydrolysis liquefaction, flash braise, saccharification, bleaching, ion exchange and enrichment of amylum material under the action of enzyme preparation; wherein the hydrolysis liquefaction uses a water heater as the braising and boiling reactor, and the water heater has an adjustable clearance for material entering into.
