DESIGN AND CONSTRUCTION OF MEAT GRINDING MACHINE

CHAPTER 1

INTRODUCTION

  • BACKGROUND OF THE STUDY

The preferred solution to meat processing is to introduce a mechanical and hygienic method of processing meat. The machine is used to force meat by means of rotating shaft under pressure through a horizontal mounted cylinder (shaft housing). At the end of the shaft housing there is a cutting system consisting of a cross-shaped knives rotating with the shaft and a stationary perforated disc (hole plate). The perforation of the hole plate normally range from 1 to 13mm. The meat is compressed by the rotating shaft, forced through the cutting system and extrudes through the hole of the hole plate after being cut by the revolving knives. The degree of grinding is determine by the size of the holes of the hole plate (Principles of Meat Processing Technology, 2014). This study presents the design of an efficient single meat grinding machine with both manual and motorized mode of operation, which can be used (in the urban and rural area) and with or without electricity. This design provides the kinematic arrangement of forces, materials selection and proportion of parts to ensure maximum strength and functionality of the machines. Meat grinders are either motorized or manually operated. This paper presents the design, construction and testing of an efficient single meat grinding machine with both manual and motorized mode of operation. The concept of the study came as a measure to design and construct a machine which can be used for grinding meat into a very smaller piece. This is as to encourage the processing of meat and the establishment of meat processing industries in Nigeria, especially in the northern parts where there is high availability of beef as a raw material

  • STATEMENT OF THE PROBLEM

 Meat is an essential nutritious food item needed for human consumption from which high quality proteins, minerals and essential vitamins are derived. However, certain categories of consumers such as the children, elderly and sick people might not be able to provide the requisite biting force for chewing of the meat. Thus they would only be able to consume meat in their grinded form. In order to address this problem, it becomes necessary to have a meat grinding machine. Meat grinders are either motorized or manually operated. This problem confronting the study is   the design, construction and testing of a meat grinding machine

 OBJECTIVE OF THE STUDY

The main objective of the study is  the design and  and construction of meat grinding machine.

The specific objective is the

  1. The description of meat grinding machine.
  2. The significance of meat grinding machine
  3. The design and and construction of meat grinding machine.

 SIGNIFICANCE OF THE STUDY

The study shall of  be of immense benefit to meat producers.It shall also provide the needed technology required for  producing meat grinding machine. Policy makers in the agro processing sector can also leverage on the technology proffered in the study.

 SCOPE OF THE STUDY

The study  is  the design and  construction of meat grinding machine.It offers a description of  meat grinding machine, significance of meat grinding machine and the design and  and construction of meat grinding machine.

  • LIMITATION OF THE STUDY

The study was confronted by the following constraint

1.TIME. The research was confronted with other academic activities which was also of immense significance in the process of conducting the study

  1. LOGISTICS. The researcher was also faced the challenge of inadequate facilities and equipments in the process of conducting the study
  2. FINANCE. The study was faced with limited finance so it also impacted on the processs of conducting the study

 

  • DEFINITION OF TERMS

MEAT PROCESSING MACHINE DEFINED

The machine is used to force meat by means of rotating shaft under pressure through a horizontal mounted cylinder (shaft housing). At the end of the shaft housing there is a cutting system consisting of a cross-shaped knives rotating with the shaft and a stationary perforated disc (hole plate). The perforation of the hole plate normally range from 1 to 13mm. The meat is compressed by the rotating shaft, forced through the cutting system and extrudes through the hole of the hole plate after being cut by the revolving knives. The degree of grinding is determine by the size of the holes of the hole plate.

PROTEINS DEFINED

The nutritional value of meat is essentially related to the content of high quality protein. High quality proteins are characterized by the content of essential aminoacids which cannot be synthesized by our body but must be supplied through our food. In this respect the food prepared from meat has an advantage over those of plant origin
