Application of Moisture Analyzer in Measuring Moisture of Lotus Filling Lotus filling is one of the most common fillings in the moon cake processing industry. Whether it is Cantonese-style moon cakes, Beijing-style moon cakes or Soviet-style moon cakes, there are many varieties with lotus root as the main filling. According to the requirements of the national standard GB19855-2005 on moon cakes officially implemented on September 2, 2006, which was officially implemented on June 2, 2006, the method for detecting the moisture content of lotus fillings during the processing of moon cakes was lightly described. And the use of the SFY-6 rapid moisture analyzer in the rapid method. Lotus filling is one of the high-sugar and high-fat fillings. In the rapid moisture measurement method, if the selected temperature is too low, the whole measurement time will be lengthened. If the temperature is too high, the coking and sugar and fat will be Evaporate and get too high data. The repeatability is not ideal and the actual moisture content is not obtained. One: direct drying method 1.1 Principle: The sample was dried in an oven at 105 ± 2 ° C under atmospheric pressure until constant weight, and the lost weight was moisture. 1.2 Instrument and equipment: 1.2.1 Analytical balance: Sensitivity 0.0001g (eg HR-200GR-200) 1.2.2 Electrothermal constant temperature drying oven; the temperature can be controlled at 105±2°C. 1.2.3 sample dish: glass or aluminum. 1.2.4 Dryer: Use calcium chloride or color changing silica as a desiccant. 1.3 Measurement steps: The sample was cleaned and baked in an oven at 105 ± 2 ° C for 1 hour, taken out, and cooled in a desiccator for 30 minutes. After constant weight, weigh on an analytical balance and record the constant weight of each sample. 5-10 g of lotus seed samples were placed in a sample dish, and the weighing results were recorded. Do not cover the sample cover, and dry it in a constant temperature dry bath at 105±2°C for 3-5 hours. Remove, cover the sample cover, place it in a desiccator for 30 minutes, weigh it, and record. Then, it was placed in a constant temperature drying oven for 1 hour, cooled, and weighed. And record. Confirm the sample constant weight. 1.4 Calculation of measurement results 1.4.1 Calculation formula: moisture (%) = {(w1-W2) / (w1-w0)} X100 In the formula: W1 - the weight of the lotus seed sample before drying and weighing the sample, G. W2——Lianrong is dried at 105±2°C in a constant temperature drying oven and weighed the constant weight of the sample dish, G. W0 - the weight of the sample weighing constant weight. Two: using the moisture analyzer rapid measurement method. 2.1 At atmospheric pressure, use a halogen heater to heat and dry until constant weight. The lost weight is moisture, and the moisture content is directly displayed on the instrument. 2.2 related technical parameters; weighing range: 60g Weighing accuracy: 10mg moisture accuracy 0.01% 2.3 Lotus nut filling material moisture parameter setting: mode: fully automatic mode The automatic alarm has been tested. Drying procedure: using a step drying method. The details are as follows: 2-3 The minute temperature is set to 160 ° C; the second temperature range is 115-120 ° C. The sampling amount of lotus seed: between 2-3g. The entire measurement time is: 5 minutes Three. Product technical parameters: 1, sample weight ≥ 0.5 g 2. Water measurement range (%): 0.01-100 3. Determination of sample weight (g): 0.5-60g 4, the maximum weighing (g): 60 5, the minimum weighing reading (g): 0.01 6, water content readability (%): 0.01 7, temperature indication range (°C): starting -180 8, communication interface: standard RS232 interface 9, baud rate: 9600 / S bit 10, communication method: MCS51 series MCU communication mode 2 11, power supply: voltage 220V ± 10% frequency 50HZ ± 1HZ 12, sample temperature: -40 ° C -50 ° C 13, working environment temperature: -5 ° C -50 ° C 14, relative humidity: ≤ 80% RH 15. Dimensions (mm): 380×205×325 16, net weight: 3.7kg Fourth, product features: 1, the detection speed is fast, only a few minutes, the measurement is accurate; 2. Small size, light weight and wide application; 3, simple operation, fully automatic testing; 4. The display part is displayed by red digital tube (7 parameters: moisture value, initial value of sample weight, final value, measurement time, initial temperature value, final value, discrimination time); 5, with the printer connection function (optional accessory). V. Description: Infrared rapid moisture analyzer, designed with the principle of pyrolysis weight, is a new type of rapid moisture detection instrument. The moisture analyzer measures the weight of the sample, and the infrared heating unit and the moisture evaporation channel quickly dry the sample. During the drying process, the moisture meter continuously measures and instantly displays the % moisture content lost by the sample, and the final determined moisture content after the drying process is completed. The value is displayed as locked. Compared with the international oven heating method, infrared heating can reach the maximum heating power in the shortest time. The sample is quickly dried at high temperature. The detection result is in good agreement with the national standard oven method, and it has substitutability and high detection efficiency. In the oven method, the general sample can be measured in just a few minutes. The instrument is simple in operation and accurate in testing. The display part adopts a red digital tube, and the indication value is clearly visible. The water value, the initial value of the sample, the final value, the measurement time, the initial value of the temperature, the final value, the discrimination time and the like can be respectively displayed. Has the ability to connect to a computer, printer. Therefore, the moisture meter can be widely used in all industries that need to quickly measure moisture, such as medicine, grain, seeds, rapeseed, tobacco, chemicals, graphite, ink, sand, sand, tea, food, meat, textile, agriculture and forestry, In the laboratory and production process in the paper, rubber, plastic, fire doors and other industries.
