Tamarind Mixing Machine
Tamarind Mixing Machine

In Thailand the many agricultural products are exported to the world market. The dry foodstuff is very popular to transfigure for value increasing. The tamarind paste can be processed to many products such as stirred tamarind candy tamarind and tamarind juice. For the tamarind juice has been used for cooking and mixing in many foods. For the Thailand factory the process to make tamarind juice start from chosen the tamarind paste separated the flesh and heating. However all processes are made by manually. Furthermore the quality of tamarind juice is incompletely-controlled based on operator experiences in order to achieve the damage and quantity decreasing. Based on this condition the process it needs to resolve a problem though engineering knowledge by using the tamarind mixing machine. The tamarind mixing machine consist of electric motor 1 HP 220 Volts AC 1425 rpm gear box ratio by 1 :40 gate agitator blade and two layer bucket with inside and outside diameter is 0.5 m. and 0.6 m respectively. In the system is operated by the electric motor transfer the power though gear box with 35.6 rpm for driving the blade and give the heat by LPG. While within the outside layer of bucket contain some water for transferring the heat to product in inside layer of bucket. The results of experiment with 70 kilograms of tamarind paste by using 0.7 kilograms of fuel. Based on using the convection of water at suitable temperature and period time at 80?C and 65 minutes respectively it found that the quantity of tamarind juice is increased by reducing burnt when compared with the original process and also illustrated to be convenient using.

The Study and Development of the Vacuum Mixer for Investment in Jewelry Production
The Study and Development of the Vacuum Mixer for Investment in Jewelry Production

Thailand is a well known country where jewelry is produced to export. The process of jewelry production needs many special skills and efficient machines. Moreover the preparation of plaster is also important in producing jewelry. This requires various stages and takes more time to do. However these problems can be eliminated by knowledge in engineering. Therefore this study aimed to develop the vacuum mixer for mixing Investment for jewelry production. The vacuum mixer consists of 12 Hp 220 volts ac electric motor with the gear which has 1:40 dimension. The whole body of the vacuum mixer is made of stainless steel. The pot for mixing the Investment is 21 em. wide and 31.5 em. high. The tub at the base for placing the pot is 29 em. wide and 21 em. high. This base is equipped with a 20 m3 per hour vacuum ventilator and a vibrating motor. This vacuum mixer is operated by the electric motor which transmits power into gear. Then the gears drive the belt to make the blade stiring the Investment and water in the pot until they are well mixed together. Then the mixture is forced to the tub at the base by the valve while the air is sucked up and the mixture of the Investment is cured until all bubbles are disappeared from the mixture. After experimenting the result revealed that the use of the vacuum mixer can reduce the steps in preparing the plaster from 8 steps to 4 steps. It can also save 52% of time allotted.

Creating and Evaluating the Effectiveness of Computer Assisted   Instruction Program for Courses of Practiced
Creating and Evaluating the Effectiveness of Computer Assisted Instruction Program for Courses of Practiced

The purposes of the research were to create and efficiency validation of computer assisted for the courses of practiced to make body of ornaments based standard 90/90 and analyse the leaning achievement of the student after by using computer assisted instruction. The subjects in the study were 17 first year diploma students enrolled in Rajamangala University of Technology Phra Nakhon. The Researcher using the experiment by let the students do until test before class And then study by using computer assisted instruction focused on practiced to basic turning. After that let students do the unit test again at the class and calculate to find out the efficiency of the computer assisted instruction and analyse the leaning achievement of students after study. The research result revealed that the efficiency of the computer assisted Instruction was efficient in standard 90/90 Moreover after learning achievement At significant level of 0.05

Creating and Evaluating the Effectiveness of Computer Assisted Instruction of subject Manufacturing Processes unit 1-4

The purposes of the research were to create computer assisted intruction for Manufacturing process subject to find out the efficency validtion of computer assisted instruction based on the standard of 90/90 and to analyse the students learning achievament after using the computer assisted instrucion. The subjects the study were 17 first-year diploma enploma engineering students enrollong at Rajamangala University of Technology Phra Nakhon. The researcher made the experiment by having the students pretest. The they studied by using the computer assisted instruction foused on practiocing basic turning. After the students had studied and had posttest the efficency of the computer assisted instruction was calculated as well as leaning achievement was analysed. The research resilt revealed that the efficiency of the computer assisted instruction was at the standard of 90/90. Morever the learning achivement after using the computer assisted instruction was different at the singificant lavel of 0.05

พฤติกรรมการบริโภคอาหารเวียดนามและความพึงพอใจที่มีต่อการบริการของร้านอาหารเวียดนามของประชาชนในกรุงเทพมหานคร กรณีศึกษา : ร้านคุณอ้อแหนมเนืองโชคชัย 4

The objective of the independent study was investigating consumers’ behavior and consumers’ satisfaction to assess the Khun Or Nam Neung ChockChai 4 Restaurant. Basic factor of demographics and satisfaction levels could provide into the 4 marketing mixed factors that includes product price place and promotion. Samples were selected from 400 persons who consume in Khun Or Nam Neung Chock Chai 4 Restaurant. Data were collected by questionnaires and analyzed using software. The results of this independent study founded that most consumers were female aged more than 45 years old (58.00%) received a bachelor degree (42.00%) company enterprise (48.00%) and average revenue more than 30000 baht per month (42.00%). The most of Vietnamese food is “Nam Neung” and the reasons that they choused because Vietnamese food was very difference taste from another. For the most satisfaction level the marketing mixed factor was place factor. For the more satisfaction level the marketing mixed factors were product factor and price factor. For the medium satisfaction level the marketing mixed factor was promotion factor.
