The Design And Construction Of A Spin Dryer

The Design And Construction Of A Spin Dryer

Abstract

The purpose of this effort is to design and construct a spin dryer that can be used to dry waste grains after brewing. This will undoubtedly reduce the amount of labor and time required to spread the spent grains out on the ground to dry them in the traditional manner. Additionally, it provides jobs for our expanding population. The ease of manufacture, upkeep, and servicing of this machine was carefully considered throughout design.

The project’s historical context is described in chapter one. The project’s literature review was covered in chapter two. The third chapter covered the synthesis of the answer and covered several options, alternative comparisons, and choosing. An attempt was made to explore design analysis and theory in chapter 4. Chapter 5 included the specifics of construction, maintenance, procedures, testing, and evaluation. It was discovered to function properly and efficiently after the testing. Material evaluation, machine cost analysis, and labor cost analysis were moved to Chapter 6. The final chapter was where we discussed the project, any recommendations, and final thoughts.

Introduction

1.1 Necessities Are Identified

Machine design is the process of building new, more effective machines while also enhancing current ones. A newer or better machine is one that has lower overall production, operation, and maintenance costs.

On the basis of these considerations, we developed a machine design that will assist in resolving issues with drying spent grains in our breweries.

How to use the leftover grains after brewing is the main issue facing breweries in the nation. However, other breweries dry and burn these leftover grains as tools. Therefore, we consider this method of recognition to be wasteful rather than economical.

This inspired us to develop a brand-new technique using an SPIN DRYER to dry these used grains to the desired moisture content. These discarded grains may play a significant role in the creation of chicken meals if they are properly dried.

With this spin dryer, the unemployed masses could find employment by building or purchasing a device for drying discarded grains and turning them into beneficial chicken feed.

In reality, we are designing this project as our contribution to the eradication of unemployment and poverty, which this current government is waging war against. It is important to note that the manufacture of a spin dryer is built in a way that even inexperienced people could operate it.

Technology can also be purchased, borrowed, or stolen. Our idea uses technology that was originally developed in the west and largely used for drying garments, but we have expanded its application to more effectively dry discarded grains to the necessary moisture content.

1.2 The Objective Of The Construction

The objectives of this project’s design and construction are as follows:

1. To create a spin dryer from scratch that will reuse leftover grains from breweries.

2. To design and build a machine that spins to dry materials quickly.

3. Create a machine with a high level of automation by designing and building it.

4. Create a machine with a shorter drying time by designing and building it.

5. To create a machine that will be simple to assemble but extremely effective.

6. To design and build a machine that will be inexpensive to run and maintain.

7. Create a machine that uses less energy by designing and building it.

8. To create a machine that might improve on an existing design while taking needy areas into consideration.

1.3 The Project’s Importance And Specification

The goal of the spin dryer design is to create a quick spinning and drying device for drying spent grains.

The machine is made to work on the principle of centrifugal motion, where the used grains are spun at high speeds away from the centers of rotation, squeezing the water out. This eliminates the need for squeezing presses to moisten the spent grains in the perforated spin tub or basket.

This device spins twice as fast as a typical dryer to remove extra water from discarded grains in minutes (nearly at a rate of 145orpm). It is made with a longer lifespan and more effective operation in mind. A 4kw (5hp) motor powers it, and as the motor spins the basket, the moisture content drains into the drum. The basket is covered to stop the wetness from splashing and is enclosed in a drum. Additionally, a mesh is included in the spinning tub to stop spent grains from escaping when spinning.

1.4.1 Scope And Limitation

The spin dryer is intended to complement existing designs and enhance them. It is also intended for usage in the chemical sector and breweries for product drying. It might potentially be used to dry wasted grains on a limited scale for the manufacturing of poultry feeds.

There are still several restrictions facing this endeavor despite the breadth this machine covers.

These are listed below:

1. One of the issues preventing the machine from meeting the standard spin dryer in western countries is the lack of the right/correct materials.

2. The spin tub/basket cleaning issue is another restriction. If material gets blocked in the holes, the drying action is significantly reduced, making continual cleaning difficult.

3. It was ineffective for drying medications in pharmacies.
