Micro-distillery in Cape Town CBD

By Logichem Admin

Increasing growth of the local craft-distilling industry persuaded Logichem to venture into this small-scale market with its first plant constructed for Pienaar & Son Distilling Co. in the Cape Town CBD.

Extensive development and proto-type testing was carried out in Logichem’s R&D facility, the challenge being the development of a solids-tolerant 150mm trayed column capable of handling an unfiltered fermentation broth.  This would enable the distiller to produce a 96.4% spirit directly from the fermenter in a single pass, a huge improvement in time and energy on the multiple pot distillation alternative.

Pienaar & Son’s distillery is equipped with a Mashing vessel for starch conversion, two Fermenters, two pot stills for gin production, and a 3-column continuous still for neutral spirit, vodka, and whisky production.

At the September 2017 Michelangelo International wine and spirit awards, when Pienaar & Son had only been in production for 9 months, it won Silver and Gold for its two gins (Empire and Orient), and double-Gold for its Waskis vodka.  Congratulations!

We look forward to tasting the Bourbon-style whisky that is currently being aged in new American oak barrels.

Cassava alcohol plant in Ghana

By Logichem Admin

Logichem successfully commissioned its first cassava-based Extra Neutral Alcohol (ENA) distillery in Ghana in July 2016.

The 10 kl/d distillery is located on a cassava farm in the Volta region, and processes 60 t/day fresh cassava tubers.  The project included CO2 collection from the Fermenters, and purification to beverage-grade liquid CO2.

It was a complete turnkey project, involving site clearing and earthworks, civil construction, and supply, erection and commissioning of all process equipment and utilities.  Maximum prefabrication of piping and trial assembly was carried out in South Africa to limited site fabrication as far as possible.  Eleven containers and a flat-rack for the boiler were required to ship the equipment to site.

Aloe extract ethanol recovery

By Logichem Admin

Logichem was recently awarded a contract for the design and supply of a solvent ethanol recovery plant for a client involved in the aloe extract business.  Ethanol is used as a solvent in the process, as a result of which it becomes diluted with water.  In order to render the ethanol re-usable, it needs to be re-concentrated.

The plant is of skid-mounted design to facilitate installation on site.  Prior to dispatch, the plant was fully assembled and functionally tested in Logichem’s workshop.  After the test, the upper column section and associated piping was dismantled and stowed for transport within the framework of the plant skid.  This enabled relatively simple and quick instalation and re-assembly on site.

The packaged plant was deliverd, erected and commisioned during November 2010, for a very satisfied client.

Quote client:  ” The system looks neat and the operation is simple.  It is seldom that you still find companies that deliver the quality of service that you have supplied!”

Expansion of Wellington Whisky Distillery

By Logichem Admin

Logichem recently completed the expansion of Distell’s Sedgwick whisky distillery, the home of the award-winning Three Ships whisky product range.

Planning for this expansion started as long ago as August 2007, with final project approval in July 2008.  The project involved the upgrade of virtually every facility on the site, infrastructure as well as production.  Project budget exceeded R150 million.  A high degree of automation was incorporated to ensure consistent quality and enable the upgraded plant to be operated by substantially the same number of personnel.

The major features of the expansion were:

  • New maize and malt off-loading and milling plant
  • New wort mashing plant
  • New Fermentation Cellar
  • New Distillation plant featuring thermo-compressor energy saving technology
  • Two new 20,000 litre copper pot stills for malt whisky
  • New Blending cellar (> 3 million litres)
  • Two new 10 t/h boilers
  • Upgrade of cooling water system
  • New Effluent treatment plant
  • New plant-wide PLC/SCADA control system
  • New electrical connection, transformers and site-wide reticulation
  • Upgrade of existing whisky and gin distillation plants and migration to new PLC/SCADA

The new Mashing and Distillation plants were supplied by Logichem on a turnkey basis, while the balance of the project (excluding civil construction) was executed by Logichem on an EPCM (engineering, procurement & construction management) basis.

The first whisky was produced on the new plant in May 2010, after a very successful start-up.

Alcohol recovery plant exported to Australia

By Logichem Admin

Logichem’s first export to Australia was commissioned in February 2010.  This was a plant designed to recover alcohol from a membrane permeate stream, emanating from a process used in the production of low-alcohol wine.  This was Logichem’s 3rd order from the client.  The other two plants were for the South African and USA markets.

The challenging feature of the Australian plant was that it had to be trailer-able, limiting the maximum height to 2,5 meters.  This is a severely uncomfortable limit for a distillation plant, requiring the column to be split into 3 sections.  The plant was of skid-mounted design, and built into a framework of 1.8m wide x 3.5m long x 2.5m high.

The plant operates under vacuum to limit the operating temperature to avoid heat-damage to the product.  The heat source is electricity, a clean and convenient source available at all cellars.  A high degree of automation is involved to limit operator supervision requirements.

Prior to shipping, the plant was fully tested and commissioned at a local host cellar, and met all its design specifications.
