A feasible way to improve the future of the beer industry in New Zealand is to reduce the costs of brewing. This would lower the costs of production, allowing the breweries to produce more beer for both the New Zealand and international market while increasing profit margins. This could be achieved by saving power, materials, time, and/or making the whole production process more efficient.

 

There are a large selection of different compounds in the unwanted substances of beer, which are currently filtered out by mechanical means, such as stray yeast cells which haven’t settled, or hop debris. Using a magnetic additive, unwanted substances can be magnetically bound to a molecule which can act like an anchoring protein. Using different forms of chemical bonding and attractions, such as covalent bonding, micelle formation, electrostatic attraction, and hydrophobic/hydrophilic interaction, the unwanted substances can be removed via electromagnetics.

 

Magnetic filters can be applied to most breweries, including both high and low production rate. The method can be modified to work with many different industries and sections within industries, meaning that there is a great potential for such a solution. The magnetic filters would completely remove the need for the whirlpool tank and so would reduce the size, energy usage, and cost of future breweries. The magnetic additive will be able to be removed whether or not it is bound to anything. This means that even if extra additive is added beyond what is required to remove the unwanted substances, the additive will still be removed by the electromagnet. There is the possibility to reuse this product by unbinding the reactants from the magnet additive, reducing the cost further.
