Laiterie de Saint-Denis-de-l’Hôtel (LSDH), one of France’s key manufacturers of liquid food and vegetable products, has commissioned industrial technology group GEA to build a new production plant for producing oat, rice and soy bases for beverages.

All process steps, from the raw material intake of grains and flour to in-line standardization, will be incorporated into the plant.

based in the Centre-Val de Loire region, LSDH is an independent French family business that was initially established as a dairy but now produces and packages various beverages and liquid foods, which are mainly retailed as store brands in the country’s major supermarket chains. 

Expanding production
With GEA’s process technology, LSDH aims to expand its position on the market for plant-based beverages. The new plant, built at the company’s headquarters in Saint-Denis-de-l’Hôtel, is part of a €300 million investment program to modernize LSDH’s production infrastructure.

For the first time, LSDH will extract the oat, rice and soy concentrate on its production line. “LSDH is significantly expanding its vertical range of manufacture. We feel very honored that the company has chosen to partner with GEA in taking this important step,” says Luc Gillis, who heads GEA’s business in France and the Maghreb countries. 

“Throughout its history, LSDH has proven that it is not only highly attuned to consumer trends but also has the foresight as a business to unreservedly embrace change. When milk quotas were introduced in 1984, LSDH began using its technology to process other foods. Now, the company is once again investing in its infrastructure and its fitness for the future.”

End-to-end process integration for plant-based products
GEA will hand over a turnkey plant for continuous extraction to LSDH. 

This entails combining processing technologies, such as soaking, milling, separation through decanting, enzyme deactivation, starch hydrolysis, blending, homogenization and pasteurization, along with the engineering expertise required to plan, automate and operate the plant. 

Heinz-Jürgen Kroner, who is responsible for liquid and filling technologies at GEA, commented on the order’s significance: “GEA regards plant-based applications as a strategic growth area, thanks not only to rising global demand for these products but also to our technology portfolio and comprehensive project experience.” 

“As a result, we can support our clients throughout the entire process, right up to providing services once production gets underway.” 

With the new plant, LSDH will produce 14 tons of soy and cereal concentrate per hour.

Trials at test centers 
While LSDH already operates several GEA UHT plants, the process engineering group will be responsible for all aspects of planning and equipping the new plant. 

Following successful tests conducted at the test centers in Ahaus and Oelde, GEA and the customer have finalized the concept, gauged plant performance and established a framework for the contract. 

“At our test centers, we prove that we can bridge disciplinary divides and get our technology and process experts on the same page to integrate the best ideas into a customized concept. That was key to winning this project,” says Kroner. 

In addition, experience gained from similar projects in China, Australia and Spain helped plan the process, he notes.

In 2019, GEA fitted out an end-to-end soybean extraction plant for one of China’s largest dairy manufacturers. 

France’s economic program for vegetable proteins
In response to growing health and sustainability trends, plant-based products made from soy and cereals in the form of beverages, cottage cheese, spreads, and other convenience foods are making inroads into French kitchens. 

The country’s sales of products in this category increased by twelve percent to 32 million liters in 2020. This demand is fueling France’s efforts to promote the production of vegetable proteins found in cereals, pulses and soybeans at a national level. 

To address consumer criticism directed at soy production conditions and reduce reliance on foreign soy imports, the French government has launched an investment program for the regional cultivation of this crop. 

LSDH is working to establish the shortest possible supply chains for high-quality regional products as part of this initiative. With the new extraction facility and the pilot plant for processing other cereal-, nut- and legume-based beverages, GEA is supporting LSDH in this endeavor and will contribute not only its technological knowledge but also its process expertise.
