walnuts are one of the most important nut crops worldwide. the area under cultivation increases every year. in 2008, the food and agriculture organization reported exports of about $17.1 billion. the country of iran is the 4th largest producer of walnuts in the world. stages from production to consumption are very important, because the condition and quality of the shelled nutmeats affects the ...

The traditional method in Iran of cracking walnut manually, using harmer or knife cutter is laborintensive, slow and tedious; besides, most mechanical crackers do not give satisfactory results in terms of kernel extraction quality. A prototype machine was developed to crack walnut. A walnut cracker was designed, constructed and tested to evaluate its performance. The cracker, which consists of ...

dehulling is an important step in walnut processing that has considerable effect on the quality, chemical and microbial properties of walnuts. improving dehulling can increase the quality of the final product. this research studied the effect of genotype and hulling method on walnut properties. one experiment was performed as a factorial in a randomized complete block design with three replicat...

Post-harvest operations have been used in order to increase the efficiency of product production. In the case of walnuts, one of the important processes for improving quality is peeling the walnut’ s shell. Because of the amount of walnuts produced in Iran and the necessity to reduce the loss of products, a device for quick removal of the walnut’ s shell is needed. This study examined and compa...

the aim of this study was to determine the formulation of silver carp fish cracker and checking qualitative changes of cracker in the four time intervals (0, 30, 60 and 90 days), during storage at room temperature. treatments consisted of dried cracker (drying time 2 hours), cracker were fried (drying time 1 hour) and the final treatment was drought cracker that fried at the end of each period....

Most modern security protocols and security applications are deened to be algorithm independent, that is, they allow a choice from a set of cryptographic algorithms for the same function. Therefore a key-search machine which is also deened to be algorithm independent might be interesting. We researched the feasibility of a universal key-search machine using the Data Encryption Standard (DES) as...

The Volume Cracker is a 3D interaction technique designed to allow rapid and intuitive visual analysis of raw volume data. However, the original Volume Cracker design was limited due to cumbersome and expensive hardware and the inability to interact with real volume data. New input devices such as the Leap Motion Controller enable 6-DOF tracking of bare hands and fingers, inspiring us to design...

Based on high dependent of many processing company palm kernel oil, quality nut cracking machine is not only necessary but also important to revitalize the production in other meup with ever increasing industrial demand. Different beaters; Swing beater (SB) and conventional type known as rigid (RB) an existing cracker were investigated using moisture content (7, 17, 26% (db)), five different sp...

sound power is considered as an excellent measure for evaluating the efficiency of noise controls as well as for comparing noise sources in workrooms. this parameter can be determined by sound pressure or intensity based methods in real conditions of workrooms. this paper aims empirically to compare these in situ methods in relation to a typical industrial machine located in workroom in terms o...
