Abstract: A method for producing biodiesel includes feeding methanol into a tank and heating methanol to a temperature above a critical temperature of methanol to obtain a supercritical methanol. A reactive matrix is fed into the tank. The reactive matrix includes acetic acid and a material oil. A molar ratio of acetic acid to the material oil is in a range from 1:1 to 5:1. A molar ratio of methanol to the material oil is in a range from 20:1 to 90:1. A supercritical carbon dioxide is fed into the tank. A total pressure of the supercritical methanol and the supercritical carbon dioxide is higher than 10 MPa. The supercritical methanol, the material oil, acetic acid, and the supercritical carbon dioxide react with each other in the tank at 240-500° C. and 8.1-50 MPa for 0.1-1.5 hours to obtain biodiesel.

Abstract: The present invention provides a method for detecting a beta-glucan having immunomodulatory activity in a human cell, which uses a test cell line that stably expresses human dectin-1 molecule on the cell surface and does not express other glucan receptors and a specific amount of a marker beta-glucan that specifically binds to human dectin-1 molecule for detection.

Abstract: A method for generating high concentration chlorine dioxide having purity over 90% by means of an electrolytic procedure using an electrolytic material prepared from NaCl and NaClO2 subject to the control of optimal operation parameters of current 80˜110 Amp, concentration of sodium chloride to be 20˜25% sodium chloride and sodium chlorite to be 5% minimum, operation temperature 55˜65° C., and material feeding speed 30˜50 ml/min. Under the effect of ClO2 after 20 minutes, no bacteria count is detectable, and bacteria count Log value of SPA water of aerobic count 1.5×105 CFU/mL is dropped by 1.46 Log CFU/g in 120 ppm ClO2. Therefore, the ClO2 preparation method of the invention is an economical and convenient process suitable for on-line continuous disinfection or sterilization application.

Abstract: A negative pressure type drying machine includes a wheeled machine base carrying an drying chamber that has the peripheral walls respectively formed of high transmittance glasses, a hygrometer/thermometer for measuring the temperature and humidity in the drying chamber, an electric heater mounted in the drying chamber at the bottom for heating the air inside drying chamber, a high pressure blower for drawing air out of the drying chamber to produce a negative pressure in the drying chamber, and a control system mounted in the wheeled machine base below the drying chamber for controlling the operation of the electric heater and the high pressure blower.

Abstract: A method of processing low-fat sweet potatoes chips having the characteristics of porosity and crispness is disclosed to include the steps of (a) cutting sweet potatoes into sweet potatoes chips, (b) blanching the sweet potatoes chips with SAPP solution, (c) pre-drying the blanched sweet potatoes chips, (d) coating the pre-dried blanched sweet potatoes chips with a shortening oil, and (e) heating the sweet potatoes chips thus obtained with a superheated steam.
